关于Wigner分布函数的推导

On derivation of Wigner distribution function

Siamak Khademi

摘要:

Wigner分布函数在量子统计力学中具有重要的意义。它在物理学的各个学科中找到应用,包括凝聚态物质,量子光学,仅举几例。Wigner分布函数是由E. 1932年的维格纳。然而,迄今为止,文献中还没有关于Wigner分布函数的解析推导。本文给出了维格纳分布函数的一个简单的解析推导。我们的推导是基于两个假设,这两个假设是:A)通过对Wigner分布函数进行积分,得到关于位形空间的动量空间分布函数B)WDF是实数。类似地,除了Wigner分布函数之外,还导出了Sobouti-Nasiri分布函数,该分布函数是虚的。

英文摘要:

Wigner distribution function has much importance in quantum statistical mechanics. It finds applications in various disciplines of physics including condense matter, quantum optics, to name but a few. Wigner distribution function is introduced by E. Wigner in 1932. However, there is no analytical derivation of Wigner distribution function in the literatures, to date. In this paper, a simple analytical derivation of Wigner distribution function is presented. Our derivation is based on two assumptions, these are A) by taking the integral of Wigner distribution function, with respect to configuration space, the momentum space distribution function is obtained B) WDF is real. Similarly, and in addition to Wigner distribution function, the distribution function of Sobouti-Nasiri, which is imaginary, is also derived.
