Abstract
Nonperturbative vacuum polarization effects are explored for a supercritical Coulomb source with in 1+1 D. Both the vacuum charge density and vacuum energy 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.
