Transitions to super-radiance in ensembles of incoherently pumped emitters
Laszlo Rassaert, Tommaso Roscilde
Super-radiance is a striking phenomenon resulting from the collective interaction of emitters with light, and it is fundamentally related to the appearance of long-range correlatio…

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…
