Phase diagram of lasing under correlated pump from GPU-accelerated Truncated Wigner dynamics
Oksana Chelpanova, Martino Stefanini, Michael O'Keeffe +1
Superradiant (SR) lasers store optical coherence in the atomic medium rather than the cavity field, but the incoherent drive that sustains inversion imposes a trade-off: local pump…

One knob to tune them all: Phase-controlled photon statistics and linewidth in partially pumped atomic ensembles
Oksana Chelpanova, Martino Stefanini, Dusan Sarenac +2
We study a minimal model of collective light emission from an incoherently driven ensemble of atoms where incoherent drive is applied to only a subset of the atoms and show that bo…

Dissipative realization of Kondo models
Martino Stefanini, Yi-Fan Qu, Tilman Esslinger +3
We demonstrate that the Kondo effect can be induced through non-linear dissipative channels, without requiring any coherent interaction on the impurity site. Specifically, we consi…
