Additional resonances for cavity-mediated laser cooling    [PDF]

Oleg Kim, Almut Beige

Here we analyse cavity-mediated laser cooling for an experimental setup with an external trap which strongly confines the motion of a particle in the direction of the cavity axis. It is shown that the stationary state phonon number exhibits three sharp minima as a function of the atom-cavity detuning due to a direct atom-phonon-photon coupling term in the system Hamiltonian. For a relatively wide range of experimental parameters, for example, when the spontaneous cavity decay rate kappa is relatively large or when the phonon frequency nu is relatively small, a previously unconsidered laser Rabi frequency-dependent resonance yields the lowest stationary state phonon number.
