A quantitative theory of coherent delocalization

A quantitative theory of coherent delocalization - Introduction and background. The propagation of a photon in a multi-armed interferometer, the transfer of electrons in a network of coupled quantum dots, the spread of electronic excitations in molecular aggregates: these are all examples of quantum transport phenomena. As opposed to a purely classical regime, quantum dynamics permits the transported entity to explore different paths simultaneously. Such coherent delocalization results in...
