计算混沌光场熵的新方法
A New Approach for Calculating Entropy of the Chaotic Light Field
摘要
熵是量子光场的一个重要物理量,我们给出求混沌光场对应的热态的新方法,即有序算符内的积分方法,在此基础上计算光场的熵十分简捷。
Abstract
Entropy is an important physical quantity in quantum optics,on with we proposed a new method for deriving thermo vacuum state of the chaotic field,as the integration method with normally ordered product of operators,which leads to calculating the entropy conveniently.
