有记忆玻色子热力学的路径积分方法：密度和关联函数
Path-integral approach to the thermodynamics of bosons with memory: Density and correlation functions
摘要：
扩展以前的工作，使用路径积分形式主义，我们推导出的一个粒子约化密度矩阵和两点关联函数的二次系统的玻色子，通过一般类的内存内核相互作用的表达式。应用所得结果研究了与外界可分辨质量简谐耦合的囚禁玻色子的密度、凝聚分数和对关联函数。
英文摘要：
Expanding upon previous work, using the path-integral formalism we derive expressions for the one-particle reduced density matrix and the two-point correlation function for a quadratic system of bosons that interact through a general class of memory kernels. The results are applied to study the density, condensate fraction and pair correlation function of trapped bosons harmonically coupled to external distinguishable masses.
