Query: Electronic and lattice properties of non-centrosymmetric superconductors
  ThTSi (T = Co, Ir, Ni, and Pt)   The theoretical studies on the electronic and lattice properties of the
series of non-centrosymmetric superconductors ThTSi, where T = Co, Ni, Ir, and
Pt are presented. The electronic band structure and crystal parameters were
optimized within the density functional theory. The spin-orbit coupling leads
to the splitting of the electronic bands and Fermi surfaces, with the stronger
effect observed for the compounds with the heavier atoms Ir and Pt. The
possible mixing of the spin-singlet and spin-triplet pairing in the
superconducting state is discussed. The phonon dispersion relations and phonon
density of states were obtained using the direct method. The dispersion curves
in ThCoSi and ThIrSi exhibit the low-energy modes along the S-N-S0 line with
the tendency for softening and dynamic instability. Additionally, we calculate
and analyse the contributions of phonon modes to lattice heat capacity.
