TUNNELING AND ANTICROSSING OF EDGE MAGNETOPLASMONS IN A QUANTUM-DOT SUPERLATTICE

We calculate edge magnetoplasmons for a superlattice of quantum dots where a uniform magnetic field is applied along the superlattice direction. The confinement is assumed parabolic. We find (a) anticrossing of the edge magnetoplasmon modes and (b) splitting of the tunneling magnetoplasmon branch. Similarities with experimental data for a quantum-dot array within a plane are discussed.
