Classical-to-quantum transition behavior between two oscillators separated in space under the action of optomechanical interaction

Abstract We propose a scheme to show that the system consisting of two macroscopic oscillators separated in space which are coupled through Coulomb interaction displays the classical-to-quantum transition behavior under the action of optomechanical coupling interaction. Once the optomechanical coupl...
