The low-lying phonon mode of the fermionic ensemble is a collective density oscillation associated with particle-hole excitations, and is mathematically analogous to the momentum side mode excitations of a bosonic condensate. The mechanical motion of the fermionic particle-hole system behaves hence as a ``moving mirror''. We derive an effective Hamiltonian for system and show that it is of the form of generic optomechanical systems. We also discuss the experimental consequences the optomechanical coupling in optical bistability and in the noise spectrum of the system.
