Inhibition of Decoherence due to Decay in a Continuum
G. S. Agarwal, M. O. Scully, H. Walther
Abstract
We propose a scheme for slowing down decay into a continuum. We make use of a sequence of ultrashort 2π-pulses applied on an auxiliary transition of the system so that there is a destructive interference between the two transition amplitudes - one before the application of the pulse and the other after the application of the pulse. We give explicit results for a structured continuum. Our scheme can also inhibit unwanted transitions.
