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…
Topologically induced avoided band crossing in an optical chequerboard lattice
Matthias Ölschläger, Georg Wirth, Thorge Kock +1
We report on the condensation of bosons in the 4th band of an optical chequerboard lattice providing a topologically induced avoided band crossing involving the 2nd, 3rd, and 4th B…
Unconventional superfluid order in the -band of a bipartite optical square lattice
Matthias Ölschläger, Georg Wirth, Andreas Hemmerich
We report on the first observation of bosons condensed into the energy minima of an -band of a bipartite square optical lattice. Momentum spectra indicate that a truly complex-v…
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…
Kinetic Thomas-Fermi solutions of the Gross-Pitaevskii equation
M. Ölschläger, G. Wirth, C. Morais Smith +1
Approximate solutions of the Gross-Pitaevskii (GP) equation, obtained upon neglection of the kinetic energy, are well known as Thomas-Fermi solutions. They are characterized by the…
