Right-eigenstate-based approach to non-Hermitian superfluidity with two-body loss
Xuezhu Liu, Ming Lu, Haiwen Liu
We theoretically explore a non-Hermitian superfluid model with complex-valued interaction, inspired by two-body loss stemming from inelastic scattering observed in ultracold atomic…

First-Order PT Phase Transition in Non-Hermitian Superconductors
Xuezhu Liu, Ming Lu, Haiwen Liu +1
The interplay between superconductivity and environmental dissipation, effectively captured by non-Hermitian Hamiltonian, is a new frontier for exotic quantum phases. We explore a…
