Localized Collective Excitations in Doped Graphene in Strong Magnetic Fields
A. M. Fischer, A. B. Dzyubenko, R. A. Roemer
We consider collective excitations in graphene with filled Landau levels (LL's) in the presence of an external potential due to a single charged donor D+ or acceptor A- impurity. W…

Exciton storage in a nano-scale Aharonov-Bohm ring with electric field tuning
Andrea M. Fischer, Vivaldo L. Campo, Mikhail E. Portnoi +1
We study analytically the optical properties of a simple model for an electron-hole pair on a ring subjected to perpendicular magnetic flux and in-plane electric field. We show how…
