Dissipation-induced instabilities of a spinor Bose-Einstein condensate inside an optical cavity

EIR Chiacchio, A Nunnenkamp - Physical Review Letters, 2019 - APS
We investigate the dynamics of a spinor Bose-Einstein condensate inside an optical cavity,
driven transversely by a laser with a controllable polarization angle. We focus on a two …

Symmetries and conservation laws in quantum trajectories: Dissipative freezing

C Sánchez Muñoz, B Buča, J Tindall… - Physical Review A, 2019 - APS
In driven-dissipative systems, the presence of a strong symmetry guarantees the existence
of several steady states belonging to different symmetry sectors. Here we show that when a …

Critical light-matter entanglement at cavity mediated phase transitions

G Chiriacò, M Dalmonte, T Chanda - Physical Review B, 2022 - APS
We consider a model of a light-matter system, in which a system of fermions (or bosons) is
coupled to a photonic mode that drives phase transitions in the matter degrees of freedom …
