Current research topic (PhD): Cavity quantum optomechanics with superconducting microwave resonators

Analogous to optical cavities, resonators for microwave frequency electromagnetic radiation can be constructed using an inductor-capacitor circuit. If a mechanical element is capacitively coupled to this microwave cavity, its motion results in a modulation of the capacitance and, therefore, the resonance frequency of the cavity. When cooled down to cryogenic temperatures (~10mK), this system is suitable for studying optomechanics – the coupling of light to mechanical motion – in a new regime, relevant to both sensing applications and fundamental science. We fabricate and experimentally study such systems and use them to implement recently proposed theoretical schemes in optomechanics.
