Abstract
The very strong electromagnetic fields present in ultraperipheral relativistic heavy-ion collisions
lead to important higher-order effects of the electromagnetic interaction. These multi-photon
exchange processes are studied using perturbation theory and the sudden or Glauber approximation.
In many important cases, the multi-photon amplitudes factorize into independent single-photon
amplitudes. These amplitudes have a common impact parameter vector, which induces correlations
