Entropy for the Quantized Field in the Atom-Field Interaction: Initial Thermal Distribution

Entropy for the Quantized Field in the Atom-Field Interaction: Initial Thermal Distribution

We study the entropy of a quantized field in interaction with a two-level atom (in a pure state) when the field is initially in a mixture of two number states. We then generalise the result for a thermal state; i.e., an (infinite) statistical mixture of number states. We show that for some specific...
