Quantum Fluctuation Dynamics of Dispersive Superradiant Pulses in a Hybrid Light-Matter System
Kevin Stitely, Fabian Finger, Rodrigo Rosa-Medina +5
We consider theoretically a driven-dissipative quantum many-body system consisting of an atomic ensemble in a single-mode optical cavity as described by the open Tavis-Cummings mod…
Real-time observation of fluctuations at the driven-dissipative Dicke phase transition
Ferdinand Brennecke, Rafael Mottl, Kristian Baumann +3
We experimentally study the influence of dissipation on the driven Dicke quantum phase transition, realized by coupling external degrees of freedom of a Bose-Einstein condensate to…
Cavity Quantum Electrodynamics with a Rydberg blocked atomic ensemble
Christine Guerlin, Etienne Brion, Tilman Essslinger +1
We propose to implement the Jaynes-Cummings model by coupling a few-micrometer large atomic ensemble to a quantized cavity mode and classical laser fields. A two-photon transition…
The Dicke Quantum Phase Transition with a Superfluid Gas in an Optical Cavity
Kristian Baumann, Christine Guerlin, Ferdinand Brennecke +1
A phase transition describes the sudden change of state in a physical system, such as the transition between a fluid and a solid. Quantum gases provide the opportunity to establish…
Dynamical Coupling between a Bose-Einstein Condensate and a Cavity Optical Lattice
Stephan Ritter, Ferdinand Brennecke, Kristian Baumann +3
A Bose-Einstein condensate is dispersively coupled to a single mode of an ultra-high finesse optical cavity. The system is governed by strong interactions between the atomic motion…
Cavity Opto-Mechanics with a Bose-Einstein Condensate
Ferdinand Brennecke, Stephan Ritter, Tobias Donner +1
Cavity opto-mechanics studies the coupling between a mechanical oscillator and a cavity field, with the aim to shed light on the border between classical and quantum physics. Here…
Cavity QED with a Bose-Einstein condensate
Ferdinand Brennecke, Tobias Donner, Stephan Ritter +3
Cavity quantum electrodynamics (cavity QED) describes the coherent interaction between matter and an electromagnetic field confined within a resonator structure, and is providing a…
