Signature of PT-symmetric non-Hermitian superconductivity in angle-resolved photoelectron fluctuation spectroscopy

We show theoretically that the measurement of a PT-symmetric non-Hermitian superconductor by angle-resolved photoelectron fluctuation spectroscopy (ARPFS) provides a particular signature. In fact, the signal is negative in a single-band case in contrast to the ARPFS signal of Hermitian superconducto...
