  journal={arXiv: Mesoscale and Nanoscale Physics},
We study the bound state spectrum and the conditions for entering a supercritical regime in graphene with strong intrinsic and Rashba spin-orbit interactions within the topological insulator phase. Explicit results are provided for a disk-shaped potential well and for the Coulomb center problem.

The critical transition of Coulomb impurities in gapped graphene

The effect of supercritical charge impurities in graphene is very similar to the supercritical atomic collapses in QED for Z > 137, but with a much lower critical charge. In this sense graphene can

Electric-dipole-induced universality for Dirac fermions in graphene.

Electric dipole effects for massive Dirac fermions in graphene and related materials show a characteristic angular asymmetry, observable in tunnel spectroscopy, however, charge transport properties inferred from scattering states are highly isotropic.

Scattering theory and ground-state energy of Dirac fermions in graphene with two Coulomb impurities

We study the physics of Dirac fermions in a gapped graphene monolayer containing two Coulomb impurities. For the case of equal impurity charges, we discuss the ground-state energy using the linear

Weakly Bound States of Elementary Excitations in Graphene Superlattice in Quantizing Magnetic Field

The spectrum of allowed energy of electron in graphene superlattice in the quantizing magnetic field is investigated. Such spectrum consists of number of so-called magnetic minibands. The width of



Stabilizing topological phases in graphene via random adsorption.

It is shown that the randomization of adatom distribution greatly weakens the intervalley scattering, but plays a negligible role in spin-orbit couplings, which turns graphene from a trivial insulator into a topological state.

Atomic collapse and quasi-Rydberg states in graphene.

Charge impurities in graphene can host an infinite family of Rydberg-like resonance states of massless Dirac particles, described by Bohr-Sommerfeld quantization of collapsing classical trajectories that descend on point charge in analogy to the hydrogenic Ryd Berg states relation with planetary orbits.

Quantum spin Hall effect in graphene.

Graphene is converted from an ideal two-dimensional semimetallic state to a quantum spin Hall insulator and the spin and charge conductances in these edge states are calculated and the effects of temperature, chemical potential, Rashba coupling, disorder, and symmetry breaking fields are discussed.

Screening of a hypercritical charge in graphene

Screening of a large external charge in graphene is studied. The charge is assumed to be displaced away or smeared over a finite region of the graphene plane. The initial decay of the screened

Intrinsic and Rashba spin-orbit interactions in graphene sheets

Starting from a microscopic tight-binding model and using second-order perturbation theory, we derive explicit expressions for the intrinsic and Rashba spin-orbit interaction induced gaps in the

Mapping Dirac quasiparticles near a single Coulomb impurity on graphene

In metals, the Coulomb potential of charged impurities is strongly screened, but in graphene, the potential charge of a few-atom cluster of cobalt can extend up to 10 nm. By measuring differences in

Magnetic field driven instability of a charged center in graphene

It is shown that a magnetic field dramatically affects the problem of supercritical charge in graphene making any charge in gapless theory supercritical. The cases of radially symmetric potential

Vacuum polarization and screening of supercritical impurities in graphene.

Screening of charge impurities in graphene is analyzed using the exact solution for vacuum polarization obtained from the massless Dirac-Kepler problem, showing the polarization distribution is shown to have a power law profile, leading to screening of the excess charge at large distances.

Coulomb impurity problem in graphene.

It is shown that the Dirac equation, when properly regularized, provides a qualitative and quantitative low energy description of the problem and shows extra features that cannot be described by theDirac equation: namely, bound state formation and strong renormalization of the van Hove singularities.
