Title: Dissipative Preparation of Phase and Number Squeezed States with Ultracold Atoms

Abstract:

I present recent work (Caballar, Diehl, Makela and Watanabe, in progress) on the development of a dissipative quantum state preparation scheme for phase- and number-squeezed states. This scheme uses a double-well configuration of an ultracold atom gas immersed in a background BEC, which acts as a dissipative reservoir of excitations. The atoms are excited from the ground state to higher energy states, then dissipatively decay back to the ground state by emitting excitations into the BEC. This process results in the ultracold atom gas being driven towards a phase- or number-squeezed state irrespective of the initial state of the gas. We present a derivation of the master equation for this scheme, and examine its physical properties. Finally, we identify a parameter regime for bosonic rubidium which demonstrates the experimental feasibility of this dissipative state preparation with current technology.
