Manfred Sigrist, Yong Baek Kim
TL;DR
This paper proposes an experiment to detect time-reversal symmetry breaking in superconductors by observing fractional flux in a Josephson junction with a specific geometry.
Contribution
It introduces a novel experimental setup to identify time-reversal symmetry breaking superconductivity through fractional flux detection.
Findings
Fractional flux observed in the proposed geometry indicates symmetry breaking.
The experiment provides a new method to distinguish superconductors with broken time-reversal symmetry.
Theoretical analysis supports the feasibility of the proposed measurement.
Abstract
A new experiment is proposed to probe the time-reversal symmetry of a superconductor. It is shown that a time-reversal symmetry breaking superconductor can be identified by the observation of a fractional flux in connection with a Josephson junction in a special geometry.
