Science Daily  April 7, 2022 In an optical resonator light is reflected between mirrors, and it interacts with the levitated nanoparticle. Such interaction can give rise to dynamical instabilities which are often considered undesirable. An international team of researchers (Austria, Switzerland) has shown how they can be used as a resource. They have shown that by properly controlling these instabilities, the resulting unstable dynamics of a mechanical oscillator inside an optical cavity leads to mechanical squeezing. They applied this approach to a silica nanoparticle coupled to a microcavity via coherent scattering. The new protocol is robust in the presence of […]
