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…
Dynamics of quantum discommensurations in the Frenkel-Kontorova chain
Oksana Chelpanova, Shane P. Kelly, Ferdinand Schmidt-Kaler +2
The ability for real-time control of topological defects can open up prospects for dynamical manipulation of macroscopic properties of solids. A sub-category of these defects, form…
Dynamics of spin-momentum entanglement from superradiant phase transitions
Oksana Chelpanova, Kushal Seetharam, Rodrigo Rosa-Medina +4
Exploring operational regimes of many-body cavity QED with multi-level atoms remains an exciting research frontier for their enhanced storage capabilities of intra-level quantum co…
Injection and nucleation of topological defects in the quench dynamics of the Frenkel-Kontorova model
Oksana Chelpanova, Shane P. Kelly, Giovanna Morigi +2
Topological defects have strong impact on both elastic and inelastic properties of materials. In this article, we investigate the possibility to controllably inject topological def…
Intertwining of lasing and superradiance under spintronic pumping
Oksana Chelpanova, Alessio Lerose, Shu Zhang +3
We introduce a quantum optics platform featuring the minimal ingredients for the description of a spintronically pumped magnon condensate, which we use to promote driven-dissipativ…
