Gap-modulated doping effects on indirect exchange interaction between magnetic impurities in graphene
Oleksiy Roslyak, Godfrey Gumbs, Danhong Huang
A dilute distribution of magnetic impurities is assumed to be present in doped graphene. We calculate the interaction energy between two magnetic impurities which are coupled via t…

Dipole-dipole interaction between a quantum dot and graphene nanodisk
Joel D. Cox, Mahi R. Singh, Godfrey Gumbs +2
We study theoretically the dipole-dipole interaction and energy transfer in a hybrid system consisting of a quantum dot and graphene nanodisk embedded in a nonlinear photonic cryst…

Photon dressed electronic states in topological insulators: Tunneling and conductance
Andrii Iurov, Godfrey Gumbs, Oleksiy Roslyak +1
The surface bound electronic states of three-dimensional topological insulators, as well as the edge states in two-dimensional topological insulators, are investigated in the prese…
