S-Wave Spin-Triplet Order in Superconductors without Inversion Symmetry:Li2Pd3BandLi

“…The Pauli principle and parity conservation then dictate that superconducting pairing states with even parity are necessarily spin-singlet, while those with odd parity must be spin-triplet [1]. In materials that lack inversion symmetry, the tie between spatial symmetry and the Cooperpair spin may be broken [2,3,4,5,6,7]. The absence of inversion symmetry along with parity-violating antisymmetric spin-orbit coupling (ASOC) allows admixture of spin-singlet and spin-triplet components.…”

“…The ASOC plays a crucial role in the determination of the superconducting state. The key point is that if a spin-triplet contribution to the superconducting gap function is to emerge, its characteristic d-vector d(k) must be parallel to g(k) (provided that the ASOC is sufficiently large) [3,4]. This leads to two gap functions ∆ ± (k) = ψ ± t | g(k) |, where each gap is defined on one of the two bands formed by the degeneracy lifting of the ASOC; ψ and t are the singlet and triplet Recent band structure calculations for these compounds [16] provide information about | g(k) |.…”

“…The existence of a spin-triplet state may be stabilized by the "inter-parity" coupling (termed e m in Ref. [4]) between singlet and triplet channels as allowed by broken inversion symmetry. This interaction can arise from el.-ph.…”

Analytical Result on Electronic States around a Vortex Core in a Noncentrosymmetric Superconductor

“…(12) are the Green functions referred to asĝ I,II on Fermi surfaces I and II; this is because the spin orbit coupling splits the Fermi surface into two surfaces by lifting the spin degeneracy. 4,5 Fermi I has a nodeless pair potential, and Fermi II has a pair potential with the line node (e.g., see Fig. 1 in ref.…”
