Superconducting piezoelectric effect

The magnetopiezoelectric effect (MPE) is a cross-coupling between an electric current and strain in metals with neither inversion symmetry nor time-reversal symmetry. Unlike the conventional piezoelectric effect, MPE allows response superconductors, as we call superconducting (SCPE). SCPE may enable without Joule heating provide probe of exotic In this paper, propose formulation calculate both two-dimensional noncentrosymmetric s-wave superconductor under in-plane magnetic field. We find that magnitude comparable to MPE. It also clarified finite total momentum Cooper pairs helical state plays crucial role SCPE.
