K. V. Samokhin
TL;DR
This paper investigates the spin susceptibility in noncentrosymmetric superconductors, revealing a significant residual susceptibility at zero temperature that increases with impurities, applicable to both clean and disordered systems.
Contribution
It provides the first detailed calculation of spin susceptibility in noncentrosymmetric superconductors considering disorder effects.
Findings
Residual spin susceptibility remains large at zero temperature.
Scalar impurities enhance the susceptibility.
Results apply to both clean and disordered superconducting systems.
Abstract
We calculate the spin susceptibility of a superconductor without inversion symmetry, both in the clean and disordered cases. The susceptibility has a large residual value at zero temperature, which is further enhanced in the presence of scalar impurities.
