AbstractWe demonstrate control of quantum dynamics in a finite model system described by a tight-binding Hamiltonian, through interaction with a multifrequency external field. Effective defects can be introduced into the lattice by a two-frequency field, and the character of the defects can be controlled by the relative phase between the two field components. These field-induced defects imply robust localization of dressed (Floquet) states on lattice sites. Implications for a spin system in crossed magnetic fields are discussed.
