Quantum graphs with time dependent bond lengths — •Daniel Waltner and Uzy Smilansky — Department of Complex Systems, Weizmann Institute of Science, Rehovot, Israel

Usually a graph is considered to be built up by vertices connected by bonds with fixed lengths. In experimental realizations of graphs, for example by optical fiber networks, the bonds usually slightly change their lengths randomly caused e.g. by thermal fluctuations. We study perturbatively the effect of these fluctuations on the properties of graphs and discuss the experimental relevance.
