Cavity optomechanics: Controlling mechanical motion with light

It is well known that mechanical forces of light can be used for the manipulation of mechanical motion in microscopic systems. Notable examples include laser cooling and laser tweezers. In this talk, I will discuss recent development on the use of mechanical forces of light to control mechanical motion in macroscopic systems. As an example of potential applications, I will also discuss our current work on quantum state mapping between optical and motional states for applications in quantum networks.
