Structure and far-infrared edge modes of quantum antidots at zero magnetic field

Condensed Matter 2009-10-31 v1

Abstract

We have investigated edge modes of different multipolarity sustained by quantum antidots at zero magnetic field. The ground state of the antidot is described within a local density functional formalism. Two sum rules, which are exact within this formalism, have been derived and used to evaluate the energy of edge collective modes as a function of the surface density and the size of the antidot.
