Evidence for Optical Cooling of Biexcitons via Polariton-assisted Dissociation Scattering in CuCl

In 1991, a study based on experimental data obtained from a block single crystal of CuCl cooled to 2 K and excited by a strong monochromatic laser beam near the exciton resonance revealed a new emission band. The band was attributed to a scattering process in which a biexciton in...
