Hydrogen on graphene: Electronic structure, total energy, structural distortions, and magnetism from first-principles calculations
D. W. Boukhvalov, M. I. Katsnelson, A. I. Lichtenstein
Density functional calculations of electronic structure, total energy, structural distortions, and magnetism for hydrogenated single-layer, bilayer, and multi-layer graphene are pe…
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…
Anomalous thermal expansion in -titanium
P. Souvatzis, O. Eriksson, M. I. Katsnelson
We provide a complete quantitative explanation for the anisotropic thermal expansion of hcp Ti at low temperature. The observed negative thermal expansion along the c-axis is repro…
Quantum-Hall activation gaps in graphene
A. J. M. Giesbers, U. Zeitler, M. I. Katsnelson +3
We have measured the quantum-Hall activation gaps in graphene at filling factors and for magnetic fields up to 32 T and temperatures from 4 K to 300 K. The gap ca…
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…
The structure of suspended graphene sheets
Jannik C. Meyer, A. K. Geim, M. I. Katsnelson +3
The recent discovery of graphene has sparked significant interest, which has so far been focused on the peculiar electronic structure of this material, in which charge carriers mim…
