25 Sep 2013 | | Abstract: | We develop a dissipative quantum state preparation scheme for the creation of
phase- and number-squeezed states. It utilizes ultracold atoms in a double-well
configuration immersed in a background BEC acting as a dissipative quantum
reservoir. We derive a master equation starting from microscopic physics, and
show that squeezing develops on a time scale proportional to 1/N, where $N$ is
the number of particles in the double well. This scaling, caused by bosonic
enhancement, allows us to make the time scale for the creation of squeezed
states very short. The lifetime of squeezed states is limited by dephasing
arising from the intrinsic structure of the setup. However, the dephasing can
be avoided by stroboscopically switching the driving off and on. We show that
this approach leads to robust stationary squeezed states. Finally, we provide
the necessary ingredients for a potential experimental implementation by
specifying a parameter regime for rubidium atoms that leads to squeezed states. | | Source: | arXiv, 1309.6436 | | Services: | Forum | Review | PDF | Favorites | |
