Quantum fluctuations in trapped time-dependent Bose-Einstein condensates
Michael Uhlmann
Quantum fluctuations in time-dependent, harmonically-trapped Bose-Einstein condensates are studied within Bogoliubov theory. An eigenmode expansion of the linear field operators pe…

Effect of fluctuations on the superfluid-supersolid phase transition on the lattice
Ralf Schützhold, Michael Uhlmann, Uwe R. Fischer
We derive a controlled expansion into mean field plus fluctuations for the extended Bose-Hubbard model, involving interactions with many neighbors on an arbitrary periodic lattice,…
