Observation of a zero-energy excitation mode in the open Dicke model
Anton Bolian, Phatthamon Kongkhambut, Christoph Georges +6
Approaching phase boundaries in many-body systems can give rise to intriguing signatures in their excitation spectra. Here, we explore the excitation spectrum of a Bose-Einstein co…
Mott transition in a cavity-boson system: A quantitative comparison between theory and experiment
Rui Lin, Christoph Georges, Jens Klinder +6
The competition between short-range and cavity-mediated infinite-range interactions in a cavity-boson system leads to the existence of a superfluid phase and a Mott-insulator phase…
Observation of a dissipative time crystal
Hans Keßler, Phatthamon Kongkhambut, Christoph Georges +3
The formation of a phase of matter can be associated with the spontaneous breaking of a symmetry. For crystallization, this broken symmetry is the spatial translation symmetry, as…
From a continuous to a discrete time crystal in a dissipative atom-cavity system
Hans Keßler, Jayson G. Cosme, Christoph Georges +2
We propose the dynamical stabilization of a nonequilibrium order in a driven dissipative system comprised an atomic Bose-Einstein condensate inside a high finesse optical cavity, p…
Dynamical density wave order in an atom-cavity system
Christoph Georges, Jayson G. Cosme, Hans Keßler +2
We theoretically and experimentally explore the emergence of a dynamical density wave order in a driven dissipative atom-cavity system. A Bose-Einstein condensate is placed inside…
Light-induced coherence in an atom-cavity system
Christoph Georges, Jayson G. Cosme, Ludwig Mathey +1
We demonstrate light-induced formation of coherence in a cold atomic gas system that utilizes the suppression of a competing density wave (DW) order. The condensed atoms are placed…
Dynamical Control of Order in a Cavity-BEC System
Jayson G. Cosme, Christoph Georges, Andreas Hemmerich +1
We demonstrate dynamical control of the superradiant transition of cavity-BEC system via periodic driving of the pump laser. We show that the dominant density wave order of the sup…
Non-destructive monitoring of Bloch oscillations in an optical cavity
H. Keßler, J. Klinder, B. P. Venkatesh +2
Bloch oscillations are a hallmark of coherent wave dynamics in periodic potentials. They occur as the response of quantum mechanical particles in a lattice if a weak force is appli…
