Abstract: Cavity electromechanics relies on parametric coupling between microwave and mechanical modes to manipulate the mechanical quantum state, and provide a coherent interface between different parts of hybrid quantum systems. High coherence of the mechanical mode… read more here.

Abstract: We demonstrate that a periodically driven quantum system can adopt a quasistationary state which is effectively much colder than a thermal reservoir it is coupled to, in the sense that certain Floquet states of the… read more here.

Abstract: Ground-state cooling of mechanical resonators is an important task in quantum optomechanics, because it is a necessary prerequisite for the creation, manipulation, and application of macroscopic mechanical coherence. Here, we propose a transient-state scheme to… read more here.

DOI: 10.1103/physrevlett.124.103602
Abstract: Optomechanical couplings involve both beam splitter and two-mode-squeezing types of interactions. While the former underlies the utility of many applications, the latter creates unwanted excitations and is usually detrimental. In this Letter, we propose a… read more here.
