Abstract
Let U be a unitary operator defined on some infinite-dimensional Hilbert space. We give a set of sufficient conditions to prove that the possible embedded bound states of U are in the domain of some power of an auxiliary self-adjoint operator A. This result is illustrated on a model of kicked quantum systems.
