Cavity QED with quantum gases: new paradigms in many-body physics

F Mivehvar, F Piazza, T Donner, H Ritsch - Advances in Physics, 2021 - Taylor & Francis
We review the recent developments and the current status in the field of quantum-gas cavity
QED. Since the first experimental demonstration of atomic self-ordering in a system …

Exploring dynamical phase transitions with cold atoms in an optical cavity

JA Muniz, D Barberena, RJ Lewis-Swan, DJ Young… - Nature, 2020 - nature.com
Interactions between atoms and light in optical cavities provide a means of investigating
collective (many-body) quantum physics in controlled environments. Such ensembles of …

Photon-mediated spin-exchange dynamics of spin-1 atoms

EJ Davis, G Bentsen, L Homeier, T Li… - Physical review …, 2019 - APS
We report direct observations of photon-mediated spin-exchange interactions in an atomic
ensemble. Interactions extending over a distance of 500 μ m are generated within a cloud of …

Formation of a spin texture in a quantum gas coupled to a cavity

M Landini, N Dogra, K Kröger, L Hruby, T Donner… - Physical review …, 2018 - APS
We observe cavity mediated spin-dependent interactions in an off-resonantly driven
multilevel atomic Bose-Einstein condensate that is strongly coupled to an optical cavity …

Spinor self-ordering of a quantum gas in a cavity

RM Kroeze, Y Guo, VD Vaidya, J Keeling, BL Lev - Physical review letters, 2018 - APS
We observe the joint spin-spatial (spinor) self-organization of a two-component Bose-
Einstein condensate (BEC) strongly coupled to an optical cavity. This unusual …

Conventional and unconventional dicke models: Multistabilities and nonequilibrium dynamics

F Mivehvar - Physical Review Letters, 2024 - APS
The Dicke model describes the collective behavior of a subwavelength–size ensemble of
two-level atoms (ie, spin-1/2) interacting identically with a single quantized radiation field of …

Interactions mediated by atoms, photons, electrons, and excitons

R Paredes, G Bruun, A Camacho-Guardian - Physical Review A, 2024 - APS
Interactions between quasiparticles mediated by a surrounding environment are ubiquitous
and lead to a range of important effects from collective modes of low-temperature quantum …

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 …

Cavity-quantum-electrodynamical toolbox for quantum magnetism

F Mivehvar, H Ritsch, F Piazza - Physical Review Letters, 2019 - APS
The recent experimental observation of spinor self-ordering of ultracold atoms in optical
resonators has set the stage for the exploration of emergent magnetic orders in quantum …

Parametrically driven dissipative three-level Dicke model

J Skulte, P Kongkhambut, H Keßler, A Hemmerich… - Physical Review A, 2021 - APS
We investigate the three-level Dicke model, which describes a fundamental class of light-
matter systems. We determine the phase diagram in the presence of dissipation, which we …
