受限玻色子的动量分布:温度依赖性

Momentum distribution of confined bosons: temperature dependence

J. Tempere, F. Brosens, L. F. Lemmens, J. T. Devreese

摘要:

导出了具有简谐相互作用的抛物型玻色子气体的动量分布函数。在玻色-爱因斯坦凝聚区域中,该动量分布基本上偏离麦克斯韦-玻尔兹曼分布。有人认为,从玻色-爱因斯坦动量分布函数的玻色气体的温度的测定是更适当的比目前使用的拟合的麦克斯韦-玻尔兹曼分布的高动量尾部。

英文摘要:

The momentum distribution function of a parabolically confined gas of bosons with harmonic interparticle interactions is derived. In the Bose-Einstein condensation region, this momentum distribution substantially deviates from a Maxwell-Boltzmann distribution. It is argued that the determination of the temperature of the boson gas from the Bose-Einstein momentum distribution function is more appropriate than the currently used fitting to the high momentum tail of the Maxwell-Boltzmann distribution.
