We study the dynamics of polarizable particles coupled to a lossy cavity mode that are transversally driven by a laser. Our analysis is performed in the regime where the cavity linewidth exceeds the recoil frequency by several orders of magnitude. Using a two-stage cooling protocol we show that the particles' kinetic energy can be reduced down to the recoil energy. This cooling protocol relies in its first stage on a high laser power such that the particles cool into a strongly self-organized pattern. This can be seen as a strongly magnetized state. In a second stage we adiabatically ramp down the laser intensity such that the particles' kinetic energy is transferred to their potential energy and the particles are "demagnetized". In this second stage we optimize the ramping speed which needs to be fast enough to avoid unwanted heating and slow enough such that the dynamics remains to good approximation adiabatic.
