Orbital optical lattices with bosons
T. Kock, C. Hippler, A. Ewerbeck +1
This article provides a synopsis of our recent experimental work exploring Bose-Einstein condensation in metastable higher Bloch bands of optical lattices. Bipartite lattice geomet…
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…
Interaction-induced chiral p_x \pm i p_y superfluid order of bosons in an optical lattice
M. Ölschläger, T. Kock, G. Wirth +3
The study of superconductivity with unconventional order is complicated in condensed matter systems by their extensive complexity. Optical lattices with their exceptional precision…
Observation of local temporal correlations in trapped quantum gases
Vera Guarrera, Peter Wuertz, Arne Ewerbeck +3
We measure the temporal pair correlation function of a trapped gas of bosons above and below the critical temperature for Bose-Einstein condensation. The measurement i…
