Intrinsic localized states and nonlinear excitations of Bloch electrons in electric fields
Abstract
Bloch electrons with Coulomb interaction will take localized motion on a discrete lattice in the electric fields. They are always oscillatory in time, with oscillatory frequencies determined by electric fields. Their nonlinear excitations are the spatially localized and time periodic or quasiperiodic, and possess multiple frequencies and comprise multiple soliton components.
