Low temperature Thermodynamics in the Context of Dissipative Diamagnetism

TL;DR

This paper investigates how quantum dissipation influences low-temperature thermodynamics in Landau diamagnetism, revealing that strong system-environment coupling significantly alters entropy and specific heat, especially with an added parabolic potential.

Contribution

It provides a detailed analysis of dissipation effects on diamagnetic thermodynamics, highlighting deviations from classical behavior at low temperatures.

Findings

Dissipation qualitatively changes low-temperature entropy and specific heat.

Strong coupling to the environment impacts thermodynamic properties.

The presence of a parabolic potential modifies dissipation effects.

Abstract

We revisit here the effect of quantum dissipation on the much - studied problem of Landau diamagnetism, and analyze the results in the light of the third law of thermodynamics. The case of an additional parabolic potential is separately assessed. We find that dissipation arising from strong coupling of the system to its environment qualitatively alters the low-temperature thermodynamic attributes such as the entropy and the specific heat.
