D. Birkedal et al., Experimental investigation of quantum effects in time-resolved resonant Rayleigh scattering from quantum well excitons, PHYS ST S-A, 178(1), 2000, pp. 5-11
Resonant Rayleigh scattering from quantum well excitons is investigated usi
ng ultrafast spectral interferometry. We isolate the coherent Rayleigh scat
tering from incoherent luminescence in a single speckle. Averaging the reso
nant Rayleigh intensity over several speckles allows us to identify feature
s in support of quantum corrections to the classical description of the und
erlying scattering process.
