Electron states in the field of charged impurities in two-dimensional Dirac systems
E. V. Gorbar, V. P. Gusynin, O. O. Sobol
We review the theoretical and experimental results connected with the electron states in two-dimensional Dirac systems paying a special attention to the atomic collapse in graphene…

Coulomb center instability in bilayer graphene
D. O. Oriekhov, O. O. Sobol, E. V. Gorbar +1
In the low-energy two-band as well as four-band continuum models, we study the supercritical instability in gapped bilayer graphene in the field of a charged impurity. It is found…

Supercritical instability of Dirac electrons in the field of two oppositely charged nuclei
O. O. Sobol
The Dirac equation for an electron in a finite dipole potential has been studied within the method of linear combination of atomic orbitals (LCAO). The Coulomb potential of the nuc…
