Statistical physics IV

Questions for the paper:

• Introduce the optomechanical interaction and its Hamiltonian
  
• What is the power spectral density (PSD) of the radiation pressure and how it related to the cooling/heating of the mechanical mode
  
• Explain how by choosing the correct cavity detuning, the interaction can result in cooling of the mechanical mode. What is the phonon occupation of the mechanical mode at the steady state.
  
• Present the complete description of the problem using the quantum Langevin equations
