Event Details & Abstract: 

The field of quantum optomechanics has seen great progress over the last decade with exciting theoretical proposals developed in parallel to impressive experimental demonstrations. In this seminar I will outline the theoretical and experimental work done during my PhD. In particular, developing detection based feedback control techniques, for example to enable feedback cooling or to stabilize parasitic instabilities.

In addition to feedback control, a real-time post-processing strategy is detailed that invalidates the use of linear feedback to enhance the performance of optomechanical sensors. Finally, a unique and promising optomechanical system is developed based on surface waves of a thin film of superfluid helium-4.
