绝热混合过程中的加热与冷却
Heating and Cooling in Adiabatic Mixing process
摘要：
利用Bogoliubov-de Gennes（BdG）方法研究了费米气体两组分绝热混合过程中相互作用对温度变化的影响。我们发现，在绝热混合过程中，绝热膨胀和吸引相互作用的竞争使系统冷却或愈合成为可能，这取决于相互作用的强度和初始温度。分别研究了体相体系和俘获体系的温度变化。
英文摘要：
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.
