一类具有热效应的α相干态

A General Type of a Coherent States with Thermal Effects

Wen-Fa Lu

摘要:

在热场动力学的框架下,我们构造了一种热化相干热态,它是具有热效应的相干态的一种一般类型,并且可以通过实验来产生。计算了坐标表示中的波函数和密度矩阵元,进而给出了位置、动量和粒子数的概率密度、平均值和方差,在特殊情况下与文献中的结果一致。所有计算都在坐标表示中执行。

英文摘要:

Within the framework of thermofield dynamics, we construct a thermalized coherent thermal state, which is a general type of the coherent state with the thermal effects and can be presumably produced experimentally. The wavefunction and the density matrix element in the coordinate repersentation are calculated, and furthermore we give the probability densities, average values and variances of the position, momentum and particle number, which in special cases are consistent with those in the literature. All calculations are performed in the coordinate representation.
