Unsharp continuous measurement of a Bose-Einstein condensate: full quantum state estimation and the transition to classicality
Moritz Hiller, Magnus Rehn, Francesco Petruccione +2
We study a Bose-Einstein condensate (BEC) in a double-well potential subject to an unsharp continuous measurement of the atom number in one of the two wells. We investigate the bac…
One-dimensional phase transitions in a two-dimensional optical lattice
Magnus Rehn, Sara Bergkvist, Anders Rosengren +4
A phase transition for bosonic atoms in a two-dimensional anisotropic optical lattice is considered. If the tunnelling rates in two directions are different, the system can undergo…
Transition from a two-dimensional superfluid to a one-dimensional Mott insulator
Sara Bergkvist, Robert Saers, Emil Lundh +3
A two-dimensional system of atoms in an anisotropic optical lattice is studied theoretically. If the system is finite in one direction, it is shown to exhibit a transition between…
