Physical Review A
Simultaneous cooling and trapping of atoms by a single cavity-field mode
András Vukics, P. Domokos
Abstract
The optical dipole trap scheme is generalized by considering the laser as a dynamical cavity field mode. For a large enough finesse, the far-detuned trapping field itself exerts a significant friction force on the atom. Unlike in free-space far-off resonance dipole traps, here the trapping is stable in the steady state. The scheme in principle applies to arbitrary linearly polarizable particles, e.g., molecules.
