Current research topic

I’m working on a project aimed at observation of quantum effects in an optomechanical system consisting of a S­3N4 nanobeam coupled to a SO2 microdisc. Such a system features high single-phonon cooperativity g0 ~ 1 that favors approaching the regime where the radiation pressure dominates thermal forces. In addition, at such high g0 and in the bad-cavity limit very efficient measurements of mechanical position can be performed. The position measurements can be used to efficiently cool down the oscillator motion down to few-phonon occupation level.
