The best temperature and body of a billow in a magneto-optical allurement is bound by the spontaneously emitted photon in cooling anniversary cycle. While the aberration in atom action gives cooling and accoutrement forces, the discharge of the spontaneously emitted photon is in a accidental direction, and accordingly contributes to a heating of the atom. Of the two ħk bliss the atom receives in anniversary cooling cycle, the aboriginal cools, and the additional heats: a simple description of laser cooling which enables us to account a point at which these two furnishings ability equilibrium, and accordingly ascertain a lower temperature limit, accepted as the Doppler cooling limit.
The body is aswell bound by the spontaneously emitted photon. As the body of the billow increases, the adventitious that the spontaneously emitted photon will leave the billow after interacting with any added atoms becomes non-zero. The absorption, by a adjoining atom, of a spontaneously emitted photon gives a 2ħk drive bang amid the abounding and arresting atom which can be apparent as a abhorrent force, agnate to coulomb repulsion, which banned the best body of the cloud.
