Dynamical aspects of steady-state subradiance: Detailed balance and its breakdown

Athreya Shankar, Simon B. Jäger, Jarrod T. Reilly +3

The dynamics of dissipative many-body quantum systems sometimes admit an emergent classical description in terms of a Markov chain even though the corresponding state space contain…

Master Equation for a Quantum Gas of Polarizable Particles in Cavities

Tom Schmit, Catalin-Mihai Halati, Tobias Donner +2

Quantum gases of atoms and molecules in optical cavities offer a formidable laboratory for studying the out-of-equilibrium dynamics of open quantum systems with long-range interact…

Phase Diagram and dynamical phases of self organization of a Bose-Einstein condensate in a transversely pumped red-detuned cavity

Julian Mayr, Maria Laura Staffini, Simon B. Jäger +2

We study a transversely pumped atomic Bose-Einstein Condensate coupled to a single-mode optical cavity, where effective atom-atom interactions are mediated by pump and cavity photo…

Collective Excitations of Dissipative Time Crystals

Gage W. Harmon, Giovanna Morigi, Simon B. Jäger

We study the dynamics of atoms interacting periodically with a dissipative optical cavity and employ Floquet theory to analyze their low-frequency behavior. By means of an effectiv…

Cooling strongly self-organized particles using adiabatic demagnetization

Simon B. Jäger

We study the dynamics of polarizable particles coupled to a lossy cavity mode that are transversally driven by a laser. Our analysis is performed in the regime where the cavity lin…
