论文摘要
我们研究了在热力学扰动理论的框架中,弱相互作用的bose气体的热力学特性。分析和数值分析粒子之间局部和非本地相互作用的情况。我们获得并比较了化学电位,熵,压力和特异性热量的温度依赖性与非相互作用气体的温度依赖性。结果为热力学特征及其在过渡温度高于过渡温度的稀原子和分子叶气中的渐近行为设定了可靠的基准。
We study thermodynamic properties of weakly interacting Bose gases above the transition temperature of Bose-Einstein condensation in the framework of a thermodynamic perturbation theory. Cases of local and non-local interactions between particles are analyzed both analytically and numerically. We obtain and compare the temperature dependencies for the chemical potential, entropy, pressure, and specific heat to those of noninteracting gases. The results set reliable benchmarks for thermodynamic characteristics and their asymptotic behavior in dilute atomic and molecular Bose gases above the transition temperature.
