Effects of periodic scattering potential on Landau quantization and ballistic transport of electrons in graphene
Godfrey Gumbs, Andrii Iurov, Danhong Huang +2
A two-dimensional periodic array of scatterers has been introduced to a single layer of graphene in the presence of an external magnetic field perpendicular to the graphene layer.…
Anisotropic plasmon-coupling dimerization of a pair of spherical electron gases
Godfrey Gumbs, Andrii Iurov, Antonios Balassis +1
We have discovered a novel feature in the plasmon excitations for a pair of Coulomb-coupled non- concentric spherical two-dimensional electron gases (S2DEGs). Our results show that…
Theory for entanglement of electrons dressed with circularly polarized light in Graphene and three-dimensional topological insulators
Andrii Iurov, Godfrey Gumbs
We have formulated a theory for investigating the conditions which are required to achieve entangled states of electrons on graphene and three-dimensional (3D) topological insulato…
Electronic properties of closed cage nanometer-size spherical graphitic particles
Godfrey Gumbs, Antonios Balassis, Andrii Iurov +1
We investigate the localization of charged particles by the image potential of spherical shells, such as fullerene buckyballs. These "spherical image states" exist within surface p…
