Spontaneous synchronization and quantum correlation dynamics of open spin systems

TL;DR

This paper investigates how open spin systems can spontaneously synchronize through a common environment, leading to sustained in-phase oscillations and quantum correlations despite detuning and environmental effects.

Contribution

It demonstrates the conditions under which spontaneous synchronization occurs in open spin systems and links this behavior to the development of quantum correlations.

Findings

Spontaneous synchronization can emerge even with detuning.

Synchronization correlates with robust quantum correlations.

Dissipative and dephasing effects influence synchronization and correlations.

Abstract

We discuss the emergence of spontaneous synchronization for an open spin-pair system interacting only via a common environment. Under suitable conditions, and even in the presence of detuning between the natural precession frequencies of the two spins, they are shown to reach a long-lasting transient behavior where they oscillate in phase. We explore the connection between the emergence of such a behavior and the establishment of robust quantum correlations between the two spins, analyzing differences between dissipative and dephasing effects.
