Current research topic (PhD)

Cavity optomechanics in the strong coupling regime

In this research project , we study the radiation pressure interaction of a high-finesse optical cavity with a membrane inside. In particular, we study the generation of non-classical states ( Schrödinger’s cat and squeezed states) of the nano-mechanical resonator in a quadratic membrane-in-the-middle setup. The Schrödinger’s cat is generated through a suitably engineered dissipative dynamics exploiting the optomechanical quadratic interaction with a bichromatically driven optical cavity mode. Moreover, we generate the stationary squeezed state of a mechanical resonator in a quadratically coupled optomechanical system, driven by a pulsed laser.
