Abstract

Nonperturbative vacuum polarization effects are explored for a supercritical Coulomb source with Z>ZcrZ>Z_{cr} in 1+1 D. Both the vacuum charge density ρvac(x)\rho_{vac}(x) and vacuum energy EvacE_{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.
