Towards optomechanical entanglement between a movable mirror and light

Can entanglement and the quantum behavior in physical systems survive at high temperatures? In this talk I will show that this is the case for a electromagnetic field mode in a optical cavity interacting with a movable mirror via radiaton pressure. The physics of optomechanical self-cooling and entanglement generation for such system will be reviewed. Also, I will show that such light-matter entanglement persists at environment temperatures above 20K using state-of-the-art experiment parameters. These results open the possibility of testing decoherence models in optomechanical systems and understand how quantum mechanics can accomplish entanglement in the macroscopic domain.
