講演: | Bose condensates in interaction with excitations – a two component space-dependent model close to equilibrium |

要旨: | A model for Bose gases is considered in the so-called ‘high-temperature range’ below the temperature T_c, where Bose-Einstein condensation sets in. The model is of nonlinear two-component type, consisting of a kinetic equation with periodic boundary conditions for the distribution function of a gas of excitations interacting with a Bose condensate, which is described by a Gross-Pitaevskii equation. Results on well-posedness and long time behaviour are proven close to equilibrium. |
