T. Inagaki et M. Aihara, THE ROLE OF QUANTUM FLUCTUATIONS IN OPTICALLY-EXCITED ELECTRON-HOLE SYSTEMS, Journal of luminescence, 66-7(1-6), 1995, pp. 473-477
The quantum fluctuation effect in optically excited electron-hole syst
ems is studied. The collective modes associated with the center-of-mas
s motion are analyzed by the random phase approximation. The correlati
on energy, which is a measure of the significance of fluctuation, is a
lso evaluated.
