Dynamical Aspects of Analogue Gravity: The Backreaction of Quantum Fluctuations in Dilute Bose-Einstein Condensates
Uwe R. Fischer
We discuss the backreaction force exerted by quantum fluctuations in dilute Bose-Einstein condensates onto the motion of the classical background, derived by an ab initio approach…
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…
Quantum backreaction in dilute Bose-Einstein condensates
Ralf Schützhold, Michael Uhlmann, Yan Xu +1
For many physical systems which can be approximated by a classical background field plus small (linearized) quantum fluctuations, a fundamental question concerns the correct descri…
