On the possibility of exciton formation in semimetals in extremely high magnetic fields. II
Abstract
The semimetal model^{ 1 } is discussed for the case of extremely high magnetic fields, such that ln( p _{0}/x) >> 1, where p _{0} is the Fermi momentum and x is the reciprocal of the Debye radius. It is shown that a symmetrical vertex has only one pole in this case. This pole is governed by the interaction constant, which includes the Coulomb logarithm, ln( p _{0}/x).
