Abstract:

Driven-disipative phase transitions in open systems provide a rich avenue for the study of many-body non-equilibrium phenomena. These systems exhibit unique properties depending on the detailed nature of their system-bath interactions, which may nontrivially alter their critical dynamics, and which are amenable to study by slow ramps across the critical point. In this talk, I will discuss Kibble-Zurek dynamics in a paradigmatic two-mode driven-dissipative system of a pair of non-degenerate parametrically coupled, optomechanical oscillators. I will detail the key theoretical aspects of the model and it's predictions on universality, which have been confirmed in experiments by our collaborators in the Vengalattore group at Cornell University.
