Bath Induced synchronization — •Sayan Roy and Giovanna Morigi — Universität des Saarlandes

Synchronization is a collective phenomenon observed in nature at various scales[1]. An important question is what are the basic ingredients leading to synchronization in the microscopic domain[2,3]. In this work, we analyze the dynamics of two qubits coupled to a chain of linear oscillators acting as a reservoir. This model is amenable to an analytical treatment, which allows us to identify the conditions when the interaction with the phononic bath induces self-sustained oscillations of the two qubits. We then discuss when these dynamics can be understood as quantum synchronization.
