Quantum decoherence phenomena in thermal assisted tunneling

TL;DR

This paper investigates how thermal interactions cause quantum decoherence, leading to the transition from quantum to classical behavior in mesoscopic spin systems, highlighting the role of environment-induced decoherence.

Contribution

It introduces a new perspective on thermal-assisted decoherence as the primary mechanism for quantum-classical transition in mesoscopic spins.

Findings

Quantum decoherence arises from thermal interactions with the environment.

Thermal effects significantly influence the quantum-to-classical transition.

The approach provides insights into controlling decoherence in spin systems.

Abstract

We propose a novel approach to the problem of a transition from quantum to classical behavior in mesoscopic spin systems. This paper is intended to demonstrate that main cause of such transitions is quantum decoherence which appear as a result of a thermal interaction between spin system and its environment.
