理想的玻色爱因斯坦凝聚体杂质间的相互作用

The interaction between contaminants in ideal Bose-Einstein condensates

运用热场动力学理论研究了一维情况下有限温度的玻色爱因斯坦凝聚体杂质间的相互作用,计算了系统的能量和杂质间的相互作用力,给出相互作用力与温度和杂质间距离的关系.研究结果有助于进一步了解玻色爱因斯坦凝聚体中杂质所带来的物理效应,并为Casimir效应和玻色-爱因斯坦凝聚的实验研究提供参考.

In this paper the interaction between contaminants of the Bose-Einstein condensed system at finite temperature is discussed by using the Thermal Field Dynamics.The system energy and Casimir force between the contaminants are obtained,the relationship of the force with temperature and distance is also discussed.These results will help us further understand the physical effect of contaminants in the Bose-Einstein condensed body and provide certain reference value to Casimir effect and the Bose-Einstein condensation experimental study.
