DAMPING IN TWO-COMPONENT BOSE GAS
DAMPING IN TWO-COMPONENT BOSE GAS
We investigate the Landau and Baliaev damping of the collective modes in a two-component Bose gas using the mean-field approximation. We show that due to the two body atom-atom interaction, oscillations of each component is coupled to the thermal excitations of the other component which gives rise to creation or …
