Stability of Impurities with Coulomb Potential in Graphene with Homogeneous Magnetic Field
arXiv:1109.5556 · doi:10.1063/1.4728982
Abstract
Given a 2-dimensional no-pair Weyl operator with a point nucleus of charge Z, we show that a homogeneous magnetic field does not lower the critical charge beyond which it collapses.
