Abstract

The cool light of light For the first time, an engineered nanomechanical object has been cooled and measured in the quantum mechanical ground state using optical methods only. It was shown in 2006 that micromirrors could be cooled down with optical radiation pressure from room temperature to about 10 K. After half a decade of concentrated efforts, Painter and colleagues now show that it is possible to use this technique to freeze out all classical motion from a nanomechanical resonator, and cool it down to its quantum ground state. Together with two recent advances in different types of mechanical system, cooled in different ways to their ground state, the path is now opened to testing quantum mechanical principles in macroscopic, mechanical systems. This work paves the way for optical control of mesoscale mechanical oscillators in the quantum regime.
