Cavity nano-optomechanics in the single-photon strong-coupling regime – SinPhoCOM
The objectives of the project are to develop and explore a novel approach in cavity nano-optomechanics so as to reach the hitherto unexplored ultrastrong coupling regime, where a single intracavity photon can have a measurable impact on the oscillator and in turn on the cavity states. This regime, a
