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…
Orbital many-body dynamics of bosons in the second Bloch band of an optical lattice
J. Vargas, M. Nuske, R. Eichberger +3
A Bose-Einstein condensate (BEC) of rubidium atoms is prepared in one of two degenerate energy minima in the second Bloch band of an optical square lattice. A subsequent oscillatio…
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…
Metastable order protected by destructive many-body interference
M. Nuske, J. Vargas, M. Hachmann +3
The phenomenon of metastability can shape dynamical processes on all temporal and spatial scales. Here, we induce metastable dynamics by pumping ultracold bosonic atoms from the lo…
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…
