    "abstract": "Although coupling to a super-Ohmic bosonic reservoir leads only to partial\ndephasing on short time scales, exponential decay of coherence appears in the\nMarkovian limit (for long times) if anharmonicity of the reservoir is taken\ninto account. This effect not only qualitatively changes the decoherence\nscenario but also leads to localization processes in which superpositions of\nspatially separated states dephase with a rate that depends on the distance\nbetween the localized states. As an example of the latter process, we study the\ndecay of coherence of an electron state delocalized over two semiconductor\nquantum dots due to anharmonicity of phonon modes.",
