Abstract:
The phenomenon of the parity violation due to weak interaction may be studied
with superconducting systems. Previous research considered the case of
conventional superconductors. We here theoretically investigate the parity
violation effect in an unconventional $p$-wave ferromagnetic superconductor,
and find that its magnitude can be increased by three orders of magnitude, as
compared to results of earlier studies. For potential experimental
observations, the superconductor UGe$_2$ is suggested, together with the
description of a possible experimental scheme allowing one to effectively
measure and control the phenomenon. Furthermore, we put forward a setup for a
further significant enhancement of the signature of parity violation in the
system considered.
