Heating and Cooling in Adiabatic Mixing process

Abstract

We study the effect of interaction on the temperature change in the process of adiabatic mixing two components of fermi gases by the real-space Bogoliubov-de Gennes (BdG) method. We find that in the process of adiabatic mixing, the competition of the adiabatic expansion and the attractive interaction make it possible to cool or heal the system depending on strength of interactions and the initial temperature. The change of temperature in a bulk system and a trapped system have been investigated respectively.
