Superconductivity in a nonhermitian system and Berezinksii classification

We have investigated the effects of nonhemriticty on superconducting states. Nonhermiticity enters our system due to electrons leaking out of/into (in case of pumping) the system. We have explicitly constructed several unconventional pairing amplitudes in nonhermitian systems in thep resence and absence of the particle-hole symmetry. We find nonhermitian dynamics induces odd frequency superconducting states, and we present the related experimental observables. We have further studied the robustness of the Berezinskii classification [1] of anomalous pairing amplitude in the presence of the nonhermiticity and shown that SP∗OT∗=−1 symmetry withstands nonhermiticity.
