The symmetries of a superconductor, e.g., time-reversaland spatial inversion symmetries, may impose importantconstraints on the pairing states. Among the previouslyinvestigatedsuperconductors,mostpossessaninversioncenterin their crystal structures, in which the Cooper pairs areeither in an even-parity spin-singlet or odd-parity spin-tripletpairing state, according to the Pauli principle and parityconservation.

Time Reversal Symmetry Breaking in noncentrosymmetric superconductor Re6Ti
We have investigated the superconducting state of the noncentrosymmetric superconductor Re6Ti (Tc = 6.0 K) using muon-spin rotation/relaxation (muSR) technique. The zero-field muon experiment shows
Unconventional Pairing State in Weakly Correlated Non-centrosymmetric Superconductors
We briefly review the recent progress on the study of weakly correlated non-centrosymmetric (NCS) superconductors, with an emphasis on their novel pairing symmetry and the upper critical field
Superconducting properties of the noncentrosymmetric superconductor TaOs
The noncentrosymmetric superconductor TaOs has been characterized using x-ray diffraction, resistivity, magnetization, and specific heat measurements. Magnetization and specific heat measurements
Nuclear spin-lattice relaxation rate in noncentrosymmetric superconductors Y2C3
Abstract For a noncentrosymmetric superconductor such as Y2C3, we consider a parity-mixing model composed of spin-singlet s-wave and spin-triplet f-wave pairing components. The d-vector in f-wave
Strong antisymmetric spin-orbit coupling and superconducting properties: the case of noncentrosymmetric LaPtSi.
TLDR
A dirty s-wave behavior is observed, which provides compelling evidence that the spin-singlet component of the mixed pairing state is highly dominant and downplays LaPtSi as a good candidate for realizing time-reversal invariant topological superconductivity.
Superconductivity in Carbide Compounds
The discovery of superconductivity in MgB2 and B-doped diamond has stimulated the search for new superconducting materials in similar systems containing light elements. In the framework of BCS
Evidence for two-gap superconductivity in the non-centrosymmetric compound LaNiC2
We study the superconducting properties of the non- centrosymmetric compound LaNiC2 by measuring the London penetration depth 1k(T), the specific heat C(T, B) and the electrical resistivity ( T, B).
A single full gap in noncentrosymmetric superconductor Re6Hf by point-contact spectroscopy
We report a point-contact spectroscopy study on the noncentrosymmetric superconductor Re6Hf with a superconducting transition temperature T c ~ 6.0 K. The point-contact conductance spectra can be

TLDR
Observations suggest CaPtAs to be a new remarkable material that links two apparently disparate classes, that of TRS-breaking correlated magnetic superconductors with nodal gaps and the weakly correlated noncentrosymmetric superconductor with broken TRS, normally exhibiting only a fully gapped behavior.
Nodeless superconductivity in noncentrosymmetric PbTaSe 2 single crystals
We report an investigation of the superconducting order parameter of the noncentrosymmetric compound PbTaSe$_2$, which is believed to have a topologically nontrivial band structure. Precise
