Kinetic Theory of the Heat Capacity of Two-Level Systems

TL;DR

This paper investigates how the heat capacity of two-level systems varies with temperature change rate and initial conditions, providing a theoretical calculation and phenomenological validation.

Contribution

It introduces a detailed kinetic theory for heat capacity in two-level systems, accounting for dynamic effects and initial states.

Findings

Heat capacity depends on temperature variation rate.

Initial system state influences heat capacity measurements.

Theoretical and phenomenological results agree.

Abstract

It is shown that measured heat capacity depends on the rate of the temperature variation and on the initial state of a system. It is calculated here in the framework of two-level model. Fenomenological approach gives the same results.
