Abstract
We perform quantum calculations of fluctuations of the electromagnetic
fields in AA collisions at RHIC and LHC energies.
Calculations are performed with the help of the
fluctuation-dissipation theorem accounting for the giant dipole and
quadrupole
resonances. We find that in the quantum picture the field fluctuations
are much weaker than that predicted by the classical Monte-Carlo
simulation
with the Woods-Saxon nuclear density used in previous analyses.
