Aspects of Cosmic Inflation in Expanding Bose-Einstein Condensates
Michael Uhlmann, Yan Xu, Ralf Schützhold
Phonons in expanding Bose-Einstein condensates with wavelengths much larger than the healing length behave in the same way as quantum fields within a universe undergoing an acceler…
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…
