Dissipation-induced squeezing

Understand

We present a method for phase and number squeezing in two-mode Bose systems using dissipation.

• The effectiveness of this method is demonstrated by considering cold Bose gases trapped in a double-well potential.
• The extension of our formalism to an optical lattice gives control of the phase boundaries of the steady-state phase diagram, and we discover a new phase characterized by a non-zero condensate fraction and thermal-like particle-number statistics.
• We also show how to perform amplitude squeezing in a single-mode system using dissipation.
