Fragmented many-body ground states for scalar bosons in a single trap
Philipp Bader, Uwe R. Fischer
We investigate whether the many-body ground states of bosons in a generalized two-mode model with localized inhomogeneous single-particle orbitals and anisotropic long-range intera…

Tunneling-induced damping of phase coherence revivals in deep optical lattices
Uwe R. Fischer, Ralf Schützhold
We consider phase coherence collapse and revival in deep optical lattices, and calculate within the Bose-Hubbard model the revival amplitude damping incurred by a finite tunneling…

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,…
