Duration: 19. 12. 2019 - 17. 9. 2022
Program: COST
Project leader: Prof. RNDr. Bužek Vladimír DrSc.
Annotation:Trapped ions are currently the most promising implementation of a quantum computer, where many essential building blocks have been developed in recent years. Moreover, magnetic field sensing with high sensitivity has been demonstrated and some of today’s best atomic clocks are based on atomic ions. These applications have the potential to revolutionise many aspects of our daily life. The aim of this COST Action “Trapped Ions: Progress in classical and quantum applications” (CA17113) is to enhance the current classical and quantum applications of trapped ions by supporting Europe-wide collaborations and knowledge exchange, and to allow these technologies to be taken a step further towards their commercialisation.

QISS - Quantum Information Structure of Spacetime

Quantum Information Structure of Spacetime

Duration: 1. 12. 2019 - 31. 8. 2022
Program: Multilaterálne - iné
Project leader: Doc. Mgr. Ziman Mário PhD.
Annotation:Recent advances in Quantum Gravity -the effort to understand the quantum properties of space and time- point to a central role played by the notion of Information: quantum theory gives the observer a role, replacing the objective spacetime substratum with an observer–dependent informational structure. Recent advances in Quantum Information have shown that information theoretical tools naturally describe evolution of quantum geometry, have explored non-trivial causal structures, and the role these can play in Quantum Computing. The convergence between these two vibrant research domains raises foundational issues that question the hearth of our understanding of the world: Is there a deep connection between Information and the nature of Space and Time? Are space and time losing their role as grounds for an objective physical reality?

Duration: 1. 1. 2021 - 31. 12. 2022
Program: JRP
Project leader: Mgr. Gendiar Andrej PhD.
Annotation:The application of quantum entanglement method, in particular tensor networks, in the context classical and quantum method, in particular tensor networks, in the context classical and quantum statistical physics has gaining traction in recent years. Tensor networks are now arising as a universal language in all disciplines of contemporary physics, ranging from atomic and condensed matter physics to high energy physics. In this project, we aim to establish a new collaboration between the Slovak and Taiwanese groups at Slovak Academy of Sciences (SAS) and National Taiwan University (NTU) in the development of algorithms and applications for the tensor network. The expertise in the SAS and NTU groups are complementary and both have extensive experience on the research on the development and application of tensor networks to various areas of physics. Combining the expertise and strengths of both teams, we can achieve the following scientific goals: (1) Development of efficient time-evolution algorithms for 1D/2D tensor networks, (2) Benchmark and improve variational algorithms in tensor networks, (3) Expand the applicability of the tensor networks to study behavior of society, (4) Extension of the existing variational tensor-based algorithms to fractal networks, and (5) Entanglement-entropy studies of hyperbolic spaces in the quantum-gravity theory.

SiUCs - Superinductor-based Quantum Technologies with Ultrastrong Couplings

Superinductor-based Quantum Technologies with Ultrastrong Couplings

Duration: 1. 4. 2020 - 31. 12. 2022
Program: ERANET
Project leader: Prof.RNDr. Grajcar Miroslav DrSc.
Annotation:Superconducting quantum circuits form one of the most promising solid state platforms for quantum computing. This success builds on the naturally large interaction between light, represented by microwave signals, and matter, embodied by superconducting qubits. Microwave photons are used at every stage of quantum information protocols: qubit manipulation, qubit readout and qubit-qubit coupling. To describe this rich and ubiquitous light-matter interaction, the community has relied so far on the conceptual tools inherited from quantum optics. However, atoms and photons interact weakly, perfectly justifying the use of the rotating wave approximation (RWA), which states that non-resonant processes can be safely neglected. The situation with superconducting circuits is quite different since qubits can literally be wired to transmission lines carrying microwave photons. And limitations of the RWA have already been pointed out for qubit readout or driven-dissipative protocols. SiUCs will follow a radically new approach: we will harness the potentiality of very large light-matter coupling -often referred to as ultra-strong coupling- instead of fighting it. In order to address this challenging approach in a controlled way, we will develop an architecture based on superinductors. Resonators and transmission lines built from such components display impedances close to the quantum of resistance (RQ~6.5 kOhms) at gigahertz frequencies, with very low losses, allowing a boost in light-matter interaction. SiUCS will more specifically focus on improving the efficiency of qubit operations involving light-matter interactions. In addition, superinductors will be used to engineer a missing device of the superconducting quantum circuit toolbox: the microwave single photon detector. Finally, unique many-body physics associated to ultrastrong couplings will be investigated thanks to purposely designed quantum simulators.

National Projects

AFM-IMASS - AFM: Imaging, manipulation, atomic-scale simulation

AFM: Zobrazovanie, manipulácia, simulácia na atomárnej škále

Duration: 1. 7. 2019 - 30. 6. 2022
Program: APVV
Project leader: prof. Ing. Štich Ivan DrSc.
Annotation:The AFM-IMASS project focuses on imaging and manipulation of surfaces and nanostructures on them using local atomic-scale SPM methods. For imaging the AFM and to a lesser extent also STM methods will be used. For atomic manipulation the AFM methods will be used and for manipulation of electronic charge the KPFM methods. All experiments will be backed up by computer simulations using mainly methods of density functional theory and, for correlated systems, by correlated electronic structure methods, QMC in particular. In order to achieve these objectives we will use the well-proven international consortium which in the last 5 years has generated several top results published in journals with highest impact factors (Nat. Phys., Nat. Commun., Nano Lett., ACS Nano, J. Am. Chem. Soc.). In addition to the Inst. of Physics SAS (group of Prof. Stich, computer modeling and simulation), this consortium consists of Dept. of Appl. Physics, Osaka University (prof. Sugawara and prof. Li, sample preparation and non-contact AFM/KPFM experiments), Dept. Appl. Phys. University Giessen (Prof. Schirmeisen, nanotribology experiments), and King's college London (prof. Kantorovich, theory and simulation). For the purpose of the AFM-IMASS project this consortium will be extended by Inst. of Physics CAS (Prof. Jelinek, AFM/KPFM of correlated systems). In line with that we envisage three principal research directions: 1) Transition metal oxide surfaces with focus on their catalytic properties, 2) Organometallic materials and polymers and their electronic properties: 1D and 2D ferrocene, and 3) Nanotribology with focus on structural superlubricity. Scientific objectives will be complemented by 4) Educational and public outreach targeting young generation. Objective of the current AFM-IMASS project will be top internationally competitive results with the ambition of publishing them in the journals with highest impact factors- part of the results in journals with impact factors >10.

Project leader: Mgr. Bartoš Erik PhD.
Annotation:We will deal with the formation of theories describing the forecasts of exchange rate developments in the financial markets as well as the dynamics of stock market developments based on strings theory. We want to develop a theory describing the physical properties of graphene, where the superconductor could by created using topological defects. We will try to extend our work for Weyl semimetals which have unique transport properties and surface state, and in some respect are really 3D analogs of graphene. We will also apply modern methods of mathematical physics in biology for investigation of electron transfer in solar systems and for use of supersymmetry in living organisms to analyze trash DNA, i. e., not active DNA in biological systems. Finally we want work also on the large-scaled systems and try to explain some cosmological question as the anisotropies presented at early stages of the universe formation and the presence of Dark Energy responsible for the accelerated expansion of the universe.

MICROPAN - Rational design of hydrogel microcapsules for immunoprotection of transplanted pancreatic islets in diabetes treatment

Cielený dizajn hydrogélových mikrokapsúl pre imunitnú ochranu pankreatických ostrovčekov v liečbe cukrovky

Duration: 7. 1. 2019 - 30. 6. 2023
Program: APVV
Project leader: Dr. Rer. Nat. Šiffalovič Peter DrSc.
Annotation:This project is devoted to our continuous effort aimed at the diabetes treatment by transplanted insulin-producing cells that are immunoprotected from the host immune system by a semipermeable polymer membrane. This membrane is in the form of a hydrogel microcapsule formed by the polyelectrolyte complexation of polyanions, the sodium alginate (SA) and sodium cellulose sulfate (SCS) with the polycation poly(methylene-co- cyanoguanidine), (PMCG). Over the past two decades we have accumulated important knowledge showing that this type of microcapsule (acronym PMCG), belongs to the family of microcapsules with a promise to reach the phase of clinical trials. There are two principal advantages of this microcapsule: (1) it exhibits biocompatibility after intraperitoneal implantation to various animal models, including the pre-clinical model of non-human primates (NHP), (2) it affords a unique ability to tailor the physico-chemical properties in correlation with in vivo performance that is not possible for other encapsulation systems. The MICROPAN project aims at the first systematic investigation for the microencapsulation system of the correlation between polymer selection, encapsulation conditions, microcapsule properties and in vivo performance. This is thanks to the availability of in- house synthesized SCS and PMCG polymers used instead of commercial polymers with inconsistent characteristics. The expected project outcome will be the library of microcapsules of predicted performance in vivo in the immunocompetent mice with the proposal to test selected microcapsules in NHPs that will be planned outside of MICROPAN project. This project will enhance our understanding of the mechanism of microcapsule formation by polyelectrolyte complexation and, hence, will contribute to the future rational designs of microcapsules for immunoprotection of transplanted cells.

HvdWH - Real-time grow studies of hybrid van der Waals heterostructures

Časovo-rozlíšené štúdium rastu hybridných van der Waalsových heteroštruktúr

Duration: 1. 7. 2018 - 30. 6. 2022
Program: APVV
Project leader: RNDr. Mrkývková Naďa PhD.
Annotation:The van der Waals heterostructures (vdWHs) are newly discovered physical structures that consist of several two-dimensional (2D) atomic layers held together by weak van der Waals forces. The vdWHs show unique functionalities that are not accessible in their three-dimensional counterparts. This project is focused on the investigation of the hybrid vdWHs (hybrid refers to the fact that at least one of the layers is organic) with large application potential in organic electronics and optoelectronics. In particular, we will investigate the growth kinetics, molecular orientation, structure and lattice parameters of organic thin films deposited on 2D substrates. The proposed research will address fundamental questions of the molecular thin film growth processes with particular emphasis on time-resolved in-situ experiments. The novelty of this project resides in the use of new and intriguing 2D materials as the substrates for the growth of organic molecular films and in a detailed investigation of this growth process in order to tailor preparation of novel hybrid vdWHs with specific properties. We will use 2D substrates with different electronic properties, namely the semimetal graphene and the semiconducting MoS2 thin films, which both have strong application potential in nowadays electronics. Regarding the organic molecules, we will concentrate on those possessing the properties beneficial for optoelectronics, such as absorption in the visible spectrum range, good electric conductivity and capability of self-assembly. We will start with pentacene and TzTz-based small molecules. We believe that such basic research is highly relevant for further development of enhanced organic electronic applications such as organic light emitting diodes, organic field effect transistors and organic solar cells.

Monocell - In situ growth process and controllable preparation of perovskite monolayer films

In situ monitorovanie rastu a riadená príprava monovrstiev perovskitov

Duration: 1. 10. 2018 - 30. 9. 2021
Program: APVV
Project leader: Dr. Rer. Nat. Šiffalovič Peter DrSc.
Annotation:Metal halide perovskites are an exciting class of materials that possess many of the attributes desirable for optoelectronic applications, with certified power-conversion efficiencies of perovskite-based photovoltaics reaching 23%. Photoluminescence quantum efficiency of thin films used in highly efficient devices is still low (~1%), which is mainly consistent with sizable density of sub-gap trap states that act as non-radiative recombination centers. In order for a solar cell to reach its theoretical performance limits, luminescence should be maximized with all non-radiative recombination eliminated. The conventional perovskite films prepared by solution process are usually composed of nanoscale grains so that there are a number of boundaries in the film. Correspondingly, a perovskite monolayer with single crystal cross-section profile is considered to be the desired active layer. The characteristics of the monolayer film are very close to that of the single crystal film. However, how to prepare a monolayer perovskites film with single crystal cross-section profile for solar cells is still a big challenge. The primary project’s objective is to identify the key mechanisms governing the formation of perovskite thin films during solution fabrication process. Accordingly, systematic understanding of perovskite crystals growth process is highly required and will be sorted out by real-time and in-situ GI-WAXS/SAXS complemented by real-time photoluminescence. The ex-situ energy-resolved electrochemical impedance spectroscopy of trap states in bandgap will be employed to elucidate the relationship between the electronic and structural properties of perovskite thin films. The principal aims of this joint research proposal are focused on understanding of growth mechanism of the perovskites, which will enable controllable fabrication of perovskite monolayer films for high efficiency solar cells.

Combination of nanoparticles and essential oils for mitigating the biodeterioration on various types of building materials

Project leader: RNDr. Hofbauerová Monika PhD.
Annotation:The aim of the research is to gain a new knowledge about of the use of various combinations of nanoparticles and superhydrophobic particles with essential oils in order to inhibite the biodeterioration of traditional as and modern building materials. Antimicrobial effects of selected essential oils with nanoparticles and superhydrophobic particles on natural materials and modern building materials, such as wood (whitewood, pine, etc.), travertine, granite, sandstone, plastics and ceramics to reducing or completely suppressing microbiological damage will be evaluated. Nanoparticles and superhydrophobic particles (SHPs) should increase the antimicrobial effect of essential oils by formation of hydrophobic barrier and thereby inhibit the growth of microorganisms.

Project leader: Mgr. Sedlák Michal PhD.
Annotation:This project aims to bring the paradigm of quantum technologies one step further by consolidating an information-processing framework for higher-order quantum structures. The goal is to extend mathematical description of quantum processes with indefinite causal order to include all possible experimental setups as well as all similar frameworks (higher order maps, process matrices, …). The project starts by investigation of limitations and complexity of such higher order quantum computation. The second objective is to study how these structures can be quantumly programed (controlled) and to develop methods for detecting coherence and causal order superposition in multi-time quantum processes.

Project leader: Ing. Nádaždy Vojtech CSc.
Annotation:The project is focused on the research of advanced organometallic perovskite solar cells (PSCs) with the interfaces modified by 2-dimensional (2D) nanomaterials to achieve improved functionality. In particular, procedures for incorporation of 2D nanosheets of graphene, graphene oxide and MoS2 will be developed and optimized in terms of basic electrical parameters such as open-circuit voltage, short-circuit current, filling factor and power conversion efficiency. Effect of 2D nanomaterials on the crystal and electronic structure of perovskite will be systematically analyzed. Here, original knowledge on the correlation between the interface quality, electronic structure and properties of electron transport is expected. The issue of stability enhancement of PSCs will be addressed separately. The project results will allow tailored preparation of PSCs with enhanced stability and with direct impact on practical applications.

Program: APVV
Project leader: Doc. Mgr. Ziman Mário PhD.
Annotation:Future quantum technologies are aiming to enhance our computational power, secure our communication, but also increase precision of our detection devices (from detectors of gravitational waves to medicine diagnostics methods). The effort of researchers included in this project is focused on optimisation of theoretical proposals, also by taking into account more realistic models reflecting the situations outside the laboratories. Our project joins the second quantum revolution on the side of theory, while aiming at mid-term quantum technology applications. We will develop novel tools and methods for improving the performance of quantum measurement, simulation and optimization devices. In particular, we aim to investigate the mathematical structure of quantum information resources in order to utilize them in novel and efficient quantum metrology applications and quantum simulations. The planned analysis of higher-order quantum structures and related optimal information processing is uncovering new quantum resouces (e.g. quantum causality, memory) that has potential to boost qualitatively the performance of quantum computation and communication technologies. Our plans to optimize tensor network algorithms by using the structure of interactions (space-time) are definitely enlarging our chances for efficient quantum simulations of physically relevant quantum many-body systems. Project tasks are divided into three workpackages aiming to optimize quantum structures, develop optimal higher-order quantum information processing and optimisation of tensor network algorithms.

Tungsten-trioxide layers for chemiresistive sensing of trace concentration of acetone vapours in air

Vrstvy trioxidu volfrámu pre chemirezistívne senzory stopových koncentrácií acetónu vo vzduchu

Duration: 1. 1. 2020 - 31. 12. 2022
Program: VEGA
Project leader: Ing. Ivančo Ján DrSc.
Annotation:Clinical studies have identified hundreds of different volatile organic compounds (VOCs) present in exhaled air of a human at concentrations in the order of ppm (10-6) or only ppb (10-9) and lower. Some VOCs are recognized as bio-markers of metabolic and physiological processes and potentially allow non-invasive health examination. For example, a healthy person has concentration of acetone vapors < 0.7 ppm, >1.7 ppm indicates a diabetes patients [1]. A sub-ppm acetone vapours sensor would allow the construction of a personal tester. The focus of the project will be a research of tungsten trioxide layers for a chemoresistive acetone sensor operating at hundred ppb. We will focus on the triclinic crystallographic phase of WO3, in which a high response to acetone adsorption has been observed. We will develop the preparation of the WO3 nanocrystalline layers with the maximum triclinic phase content, and study its effect on the sensory response and explore other WO3-based systems to increase sensing response.
