Cavity optomechanics with nm-thick membranes

Abstract:

This thesis focuses on fast and sensitive readout of mechanical motion to answer questions in the foundations of physics. By coupling a silicon nitride membrane to different readout cavities I have explored the thermodynamic costs of time keeping and carried out a bench-top experiment to put bounds on the theory of classical channel gravity. In order to reach these aims, I have developed real time displacement measurements of the motion of a nm-thick silicon nitride membrane. For this, a l...
