Emerging Non-Hermitian Topology in a Chiral Driven-Dissipative Bose-Hubbard Model

Laszlo Rassaert, Tomás Ramos, Tommaso Roscilde +1

We introduce a driven-dissipative Bose-Hubbard chain describing coupled lossy photonic modes, in which time-reversal symmetry is broken by a coherent drive with a uniform phase gra…
