Universal dynamical control of quantum mechanical decay: Modulation of the coupling to the continuum

Abstract

We derive and investigate an expression for the dynamically modified decay of states coupled to an arbitrary continuum. This expression is universally valid for weak temporal perturbations. The resulting insights can serve as useful recipes for optimized control of decay and decoherence.
