Quantum stochastic description of collisions in a canonical Bose gas
Patrick Navez, Achilleas Lazarides
We derive a stochastic process that describes the kinetics of a one-dimensional Bose gas in a regime where three body collisions are important. In this situation the system becomes…

Sauter-Schwinger like tunneling in tilted Bose-Hubbard lattices in the Mott phase
Friedemann Queisser, Patrick Navez, Ralf Schützhold
We study the Mott phase of the Bose-Hubbard model on a tilted lattice. On the (Gutzwiller) mean-field level, the tilt has no effect -- but quantum fluctuations entail particle-hole…
