Аннотация
The instability of electron-positron vacuum in strong electric fields is studied. First, falling to the Coulomb center is discussed at Z>137/2 for a spinless boson and at Z>137 for electron. Subsequently, focus is concentrated on description of deep electron levels and spontaneous positron production in the field of a finite-size nucleus with the charge Z>Z(cr) similar or equal to 170. Next, these effects are studied in application to the low-energy heavy-ion collisions. Subsequently, we consider phenomenon of "electron condensation" on levels of upper continuum crossed the boundary of the lower continuum epsilon = -m in the field of a supercharged nucleus with Z >> Z(cr). Finally, attention is focused on many-particle problems of polarization of the quantum electrodynamics (QED) vacuum and electron condensation at ultra-short distances from a source of charge. We argue for a principal difference of cases, when the size of the source is larger than the pole size rpole, at which the dielectric permittivity of the vacuum reaches zero and smaller rpole. Some arguments are presented in favor of the logical consistency of QED. All of the problems are considered within the same relativistic semiclassical approach.
