Aspects of Topology and Quantum Interference in Single Molecule Transport
Daniel Hernangomez, *Ferdinand Evers
University of Regensburg, Germany
Single molecules offer a fascinating testbed of effects that can be understood in terms of quantum interference and topology. The first part of the talk will recall counting rules that allow to predict occurrences of strong destructive interference in conjugate organic molecules. The second part is devoted to topological aspects of transport in quantum wires that can be rationalized within the Su-Schrieffer-Heeger model. An outlook towards experimental realizations will be offered at the end.
