Macroscopic Thermal Entanglement Due to Radiation Pressure
Aires Ferreira, Ariel Guerreiro, Vlatko Vedral · Physical Review Letters · 2006
Can entanglement and the quantum behavior in physical systems survive at arbitrary high temperatures? In this Letter we show that this is the case for a electromagnetic field mode in an optical cavity with a movable mirror in a thermal state. We also identify two different dynamical regimes of generation of entanglement separated by a critical coupling strength.
