TL;DR
This paper investigates how thermal noise can induce synchronization in quantum tunneling within spin-boson systems, especially under strong system-bath coupling, with implications for molecular charge transfer.
Contribution
It reveals that thermal noise can facilitate quantum synchronization at high coupling strengths, a novel insight into quantum dynamics under environmental influence.
Findings
Synchronization occurs at strong coupling (a>1).
Thermal noise aids in frequency and phase synchronization.
Application demonstrated in molecular charge transfer.
Abstract
We study within the spin-boson dynamics the synchronization of quantum tunneling with an external periodic driving signal. As a main result we find that at a sufficiently large system-bath coupling strength (Kondo parameter a>1) the thermal noise plays a constructive role in yielding both a frequency and a phase synchronization in a symmetric two-level system. Such riveting synchronization occurs when the driving frequency supersedes the zero temperature tunneling rate. As an application evidencing the effect, we consider a charge transfer dynamics in molecular complexes.
