Vortex quantum creation and winding number scaling in a quenched spinor Bose gas
Michael Uhlmann, Ralf Schützhold, Uwe R. Fischer
Motivated by a recent experiment, we study non-equilibrium quantum phenomena taking place in the quench of a spinor Bose-Einstein condensate through the zero-temperature phase tran…
Global singularity-free solution of the Iordanskii force problem
Markus Flaig, Uwe R. Fischer
We present a derivation of the transverse force acting on a hydrodynamic vortex in the presence of an incoming sound wave from a global solution of the scattering problem, using th…
A Quantum Top Inside a Bose Josephson Junction
Ingrid Bausmerth, Uwe R. Fischer, Anna Posazhennikova
We consider an atomic quantum dot confined between two weakly-coupled Bose-Einstein condensates, where the dot serves as an additional tunneling channel. It is shown that the thus-…
Sweeping from the superfluid to Mott phase in the Bose-Hubbard model
Ralf Schützhold, Michael Uhlmann, Yan Xu +1
We study the sweep through the quantum phase transition from the superfluid to the Mott state for the Bose-Hubbard model with a time-dependent tunneling rate . In the experim…
