Stability of quasi-two-dimensional Bose-Einstein condensates with dominant dipole-dipole interactions
Uwe R. Fischer
We consider quasi-two-dimensional atomic/molecular Bose-Einstein condensates with both contact and dipole-dipole interactions. It is shown that, as a consequence of the dimensional…
Mean-field expansion in Bose-Einstein condensates with finite-range interactions
Ralf Schützhold, Michael Uhlmann, Yan Xu +1
We present a formal derivation of the mean-field expansion for dilute Bose-Einstein condensates with two-particle interaction potentials which are weak and finite-range, but otherw…
Maximal length of trapped one-dimensional Bose-Einstein condensates
Uwe R. Fischer
I discuss a Bogoliubov inequality for obtaining a rigorous bound on the maximal axial extension of inhomogeneous one-dimensional Bose-Einstein condensates. An explicit upper limit…
Quantum simulation of cosmic inflation in two-component Bose-Einstein condensates
Uwe R. Fischer, Ralf Schützhold
Generalizing the one-component case, we demonstrate that the propagation of sound waves in two-component Bose-Einstein condensates can also be described in terms of effective sonic…
Quasiparticle universes in Bose-Einstein condensates
Uwe R. Fischer
Recent developments in simulating fundamental quantum field theoretical effects in the kinematical context of analogue gravity are reviewed. Specifically, it is argued that a curve…
Dynamical role of anyonic excitation statistics in rapidly rotating Bose gases
Uwe R. Fischer
We show that for rotating harmonically trapped Bose gases in a fractional quantum Hall state, the anyonic excitation statistics in the rotating gas can effectively play a {\em dyna…
