Controlling coherence via tuning of the population imbalance in a bipartite optical lattice
M. Di Liberto, T. Comparin, T. Kock +3
The control of transport properties is a key tool at the basis of many technologically relevant effects in condensed matter. The clean and precisely controlled environment of ultra…
Observing Chiral Superfluid Order by Matter-Wave Interference
T. Kock, M. Ölschläger, A. Ewerbeck +3
The breaking of time reversal symmetry via the spontaneous formation of chiral order is ubiquitous in nature. Here, we present an unambiguous demonstration of this phenomenon for a…
Nonequilibrium Phase Transition of Interacting Bosons in an Intra-Cavity Optical Lattice
M. Reza Bakhtiari, Andreas Hemmerich, Helmut Ritsch +1
We investigate the nonlinear light-matter interaction of a Bose-Einstein condensate trapped in an external periodic potential inside an optical cavity which is weakly coupled to va…
Dynamical phase transition in the open Dicke model
J. Klinder, H. Keßler, M. Wolke +2
The Dicke model with a weak dissipation channel is realized by coupling a Bose-Einstein condensate to an optical cavity with ultra-narrow bandwidth. We explore the dynamical critic…
Steering matter wave superradiance with an ultra-narrowband optical cavity
H. Keßler, J. Klinder, M. Wolke +1
A superfluid atomic gas is prepared inside an optical resonator with an ultra-narrow band width on the order of the single photon recoil energy. When a monochromatic off-resonant l…
Orbital superfluidity in the -band of a bipartite optical square lattice
Georg Wirth, Matthias Ölschläger, Andreas Hemmerich
The successful emulation of the Hubbard model in optical lattices has stimulated world wide efforts to extend their scope to also capture more complex, incompletely understood scen…
