Collective light forces on atoms in resonators
We study resonator-induced light forces arising from cooperative atom–light interaction. For such collective processes, the force on the sample can be orders of magnitude larger than the sum of conventional light forces on individual atoms. Since resonator-induced light forces can be dissipative even when the incident light is far detuned from atomic transitions, they may be applicable to target particles with a complex level structure.

Abstract A new repulsive term in the ionic interaction potential ψ ( r ) = Ar −n e − r / gl , is suggested and the three unknown parameters A , λ and n are evaluated. Lattice energies of alkali halide crystals are calculated using this form. The results agree fairly well with the experimental values.
