  We investigate the effects of dynamical Casimir effect in superradiant light
scattering by Bose-Einstein condensate in an optomechanical cavity. The system
is studied using both classical and quantized mirror motions. The cavity
frequency is harmonically modulated in time for both the cases. The main
quantity of interest is the number of intracavity scattered photons. The system
has been investigated under the weak and strong modulation. It has been
observed that the amplitude of the scattered photons is more for the classical
mirror motion than the quantized mirror motion. Also, initially, the amplitude
of scattered photons is high for lower modulation amplitude than higher
modulation amplitude. We also found that the behaviour of the plots are similar
under strong and weak modulation for the quantized mirror motion.
