The discovery of superconductivity in materials with broken inversion symmetry has triggered great interest in the study of their electronic structure and its relation to the formation of a superconducting condensate. The absence of inversion symmetry in these so-called non-centrosymmetric (NCS) superconductors allows non-trivial states such as the mixing of spin-singlet and triplet components into a superconducting pairing or Ising superconductivity in 2D systems with extremely high values of the critical magnetic field. NCS superconductivity has been shown in most 2D monolayers and several bulk systems, such as La3Se4, CeRh2As2, TaIrB2, and others. Within the scope of this dissertation, we will study the superconducting properties of various bulk NCS superconductors. We plan to study the effect of broken inversion symmetry in these systems on their band structure and on the critical magnetic fields.
