A Physical Explanation for Tilde System in Thermo Field Dynamics
摘要：
对于两体量子系统，任何纯态都可以通过Schmidt分解用双正交表示。将其应用于热力学系统及其周围环境的复合系统中，发现热场动力学中的波浪形系统正是真实系统的周围环境。
英文摘要：
For a two-body quantum system, any pure state can be represented by a biorthogonal expression by means of Schmidt decomposition. Using this in the composite system which include a thermodynamic system and its surroundings, it is found that the tilde system in thermo field dynamics is just the surroundings of the real system.
