Atomic Collapse and Quasi-Rydberg States in Graphene
A. V. Shytov, M. I. Katsnelson, L. S. Levitov
Charge impurities in graphene can host an infinite family of Rydberg-like resonance states of massless Dirac particles. These states, appearing for supercritical charge, are descri…

Vacuum Polarization and Screening of Supercritical Impurities in Graphene
A. V. Shytov, M. I. Katsnelson, L. S. Levitov
Screening of charge impurities in graphene is analyzed using the exact solution for vacuum polarization obtained from the massless Dirac-Kepler problem. For the impurity charge bel…
