Lecture
This lecture covers the quantum mechanical description of optomechanical systems, focusing on the Hamiltonian formulation and quantum Langevin equations. Topics include the optomechanical coupling, radiation force, photon flux, and the linearization around the driven cavity. The lecture also discusses the quantum Langevin equations, the coupling between the system and bath, dissipation and fluctuation terms, and the linearization of the interaction Hamiltonian.
