Contribution

It offers a novel analysis of the connection between thermal state structures and the onset of Zeno dynamics in quantum systems.

Findings

Temperature enhances effective couplings between quantum states.

Thermal states can establish regimes where Zeno dynamics occur.

Physical mechanisms linking temperature and Zeno phenomena are elucidated.

Abstract

Temperature can be responsible for strengthening effective couplings between quantum states, determining a hierarchy of interactions, and making it possible to establish such dynamical regimes known as Zeno dynamics, wherein a strong coupling can hinder the effects of a weak one. The relevant physical mechanisms which connect the structure of a thermal state with the appearance of special dynamical regimes are analyzed in depth.
