NONEQUILIBRIUM STEADY STATES WITH BOSE–EINSTEIN CONDENSATES

S. TASAKI, Luigi Accardi

Recently, nonequilibrium steady states (NESS) are intensively studied by several methods.In this article, NESS of a harmonic oscillator interacting with two freeboson reservoirs at different temperatures and/or chemical potentials are studied by the stochastic limit approach and the C* algebraic approach.Their interrelation is investigated as well.

In this paper, we consider two-component Bose-Einstein condensates with an internal atomic Josephson junction in the general case, i.e., 0 < p < $\frac{2}{(d-2)^+}$ . We prove existence and uniqueness results for the ground states, and obtain some properties of the ground states with large parameters.
