Title:	Structure and far-infrared edge modes of quantum antidots at zero magnetic field
Author:	Emperador, Agustí; Pi Pericay, Martí; Barranco Gómez, Manuel; Lipparini, Enrico; Serra, Llorenç
Other authors:	Universitat de Barcelona
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.
