Fluctuations and steady-state of a Bose-Einstein condensate interacting with a bath of thermal atoms
Technical Digest - European Quantum Electronics Conference (1998) 49
Abstract:
A master equation for the reduced density operator of the Bose-Einstein condensate was formulated using the quantum kinetic theory. The steady state of the system is calculated and the effect of the one-, two-, and three-particle losses on the condensate is investigated. The effect of trap losses on the particle statistics is also studied. The condensate particles are coherently pumped into an untrapped internal energy level and fall down in gravity. The relation between the statistics of the trapped condensate particles and the statistics of the particles arriving at an atom detector positioned below the condensate are derived.Cold bosonic atoms in optical lattices
