Linear optical response from the odd parity Bardasis-Schrieffer mode in locally non-centrosymmetric superconductors

Changhee Lee, Suk Bum Chung

On the recent report of a magnetic field induced first order transition between an even-parity superconductivity and an odd-parity superconductivity in $\mathrm{CeR}{\mathrm{h}}_2\mathrm{A}{\mathrm{s}}_2$, t…
