The search for unconventional superconductors has been a cornerstone of research in condensed matter physics for many years. Recently a key research interest has been superconducting materials with non-centrosymmetric (NCS) crystal structures. The lack of inversion symmetry leads to an antisymmetric spin-orbit coupling, a split Fermi surface, and the potential for upper critical fields that are vastly more than the Pauli paramagnet limiting field. Theoretical predictions expect that NCS superconductors are also prime candidates for realising a highly unconventional superconducting ground state that is an admixture of spin-triplet and spin-singlet Cooper pairs.In this proposal, we intend to study superconducting ground state properties of noncentrosymmetric TaOs using TF and LT modes to understand the pairing mechanism of non-centrosymmetric superconductor TaOS.
