Abstract
Tunneling dynamics in metastable and bistable potentials driven by correlat ed noise is studied. For barriers fluctuating randomly in time we show by e xact numerical and approximate analytical calculations the significant impa ct on the incoherent and coherent decay. Thereby we make use of both a stoc hastic Schrodinger equation and the corresponding exact master equation. Th e crucial role of synchronization of barrier flippings with intrinsic syste m dynamics is revealed.
