Suppression of thermally activated escape by heating — •Sebastian Getfert and Peter Reimann — Universität Bielefeld, Fakultät für Physik, 33615 Bielefeld, Germany

The problem of thermally activated escape over a potential barrier is solved by means of path integrals for one-dimensional reaction dynamics with very general time-dependences. For a suitably chosen, but still quite simple static potential landscape, the net escape rate may be substantially reduced by temporally increasing the temperature above its unperturbed, constant level [1].
