Quasi-particles in quantum
materials have finite lifetimes due to dissipation or interaction, enabling
their description in non-Hermitian Hamiltonians.
In this talk, I will explain how such non-Hermiticity provides new topological structures. In particular, Idiscuss enhanced supercurrents in dissipative Josephson junctions.
