Effect of realistic interatomic interactions and two-body correlation on the heat capacity of a trapped BEC
arXiv:0906.5426 · doi:10.1088/0953-4075/42/21/215302
Abstract
An approximate many-body theory has been used to calculate the heat capacity and the condensate fraction of a BEC with effective repulsive interaction. The effect of interactions has been analyzed and compared with the non-interacting case. It has been found that the repulsive interaction lowers the critical temperature from the value found in the non-interacting case. The difference between the critical temperatures increases with the increase in the total number of atoms in the trap.
