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…

User-friendly TWA for dissipative spin dynamics
Hossein Hosseinabadi, Oksana Chelpanova, Jamir Marino
We put forward a user-friendly framework of the truncated Wigner approximation (TWA) for dissipative quantum many-body systems. Our approach is computationally affordable and it fe…
