Abstract

Nonperturbative vacuum polarization effects are explored for a supercritical Coulomb source with Z>Z_cr in 1+1 D. Both the vacuum charge density ρ_vac(x) and vacuum energy E_vac are considered. It is shown that in the overcritical region the behavior of vacuum energy could be significantly different from perturbative quadratic growth up to decrease reaching large negative values.
