What is an optomechanical system?
Broadly speaking, optomechanics studies the coupling between light and (usually macroscopic) mechanical objects. More specifically, we are interested in systems in which mechanical oscillators are coupled to one or more modes of an electromagnetic field (light, microwave) through a radiation-pressure-type interaction.
In my activity I try to achieve a regime in which quantum properties of these systems become relevant. To this end, I investigate the so-called strong coupling regime, in which electromagnetic and mechanical modes are strongly coupled to each other. Does the physics of these systems correspond to anything known in other context, such as condensed matter physics? Can we exploit their properties for quantum information and communication purposes?
