Abstract
We present a quantum theory of collective excitations in a two-dimensional array of quantum dots. The collective excitations are induced by Coulomb coupling of the quantum dots, and can have energies significantly higher than the energy-level splittings in individual quantum dots. These collective excitations should be experimentally detectable.Keywords
