Effect of Giant Resonances on Fluctuations of Electromagnetic Fields in Heavy Ion Collisions

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 taking into account 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.
