Correlated Coherent States - Quantum Analogue Of Thermal States.(On The Problem Of Incorporating Thermodynamics Into Quantum Theory)

TL;DR

This paper argues that correlated coherent states are the most suitable quantum analogues of thermal states, providing a consistent explanation for quantum thermal effects in equilibrium with stochastic environments across all temperatures.

Contribution

It introduces correlated coherent states as the quantum counterparts to thermal states, addressing the integration of thermodynamics into quantum theory.

Findings

CCSs are the most adequate quantum analogues of thermal states

Quantum thermal effects can be explained using CCSs at any temperature

Provides a framework for incorporating thermodynamics into quantum mechanics

Abstract

In this paper, we show that correlated coherent states (CCSs) are the most adequate candidates for the role of quantum analogues of the thermal states. The main result of our study reduces to the fact that quantum thermal effects under conditions of the equilibrium of an object with the stochastic environment at any temperatures can be explained consistently only on the basis of the set of CCSs.
