The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are
exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as …

A colloquium-style introduction to two electronic processes in a carbon monolayer
(graphene) is presented, each having an analog in relativistic quantum mechanics. Both …

We analyze bound modes of two-dimensional massless Dirac fermions confined within a
hyperbolic secant potential, which provides a good fit for potential profiles of existing top …

We calculate the conductance G of a bipolar junction in a graphene nanoribbon, in the high-
magnetic-field regime where the Hall conductance in the p-doped and n-doped regions is 2 …

We examine a graphene quantum dot formed by combining an electric and a uniform
magnetic field. The electric field creates a smooth quantum well potential while the magnetic …

The properties of a two-dimensional electron are investigated in the presence of a circular
step magnetic-field profile. Both electrons with parabolic dispersion as well as Dirac …

We generalize the known solution of the Schrödinger equation, describing a particle
confined to a triangular area, for a triangular graphene quantum dot with armchair-type …

The present paper discusses magnetic confinement of the Dirac excitations in graphene in
the presence of inhomogeneous magnetic fields. In the first case a magnetic field directed …

Motivated by recent experiments and a theoretical analysis of the gap equation for the
propagator of Dirac quasiparticles, we assume that the physics underlying the recently …
