Kottos Group Co-Authors Paper on Fidelity in Quasi Systems

Tsampikos Kottos, assistant professor of physics; Joshua Bodyfelt Ph.D ’09; and Mei Zheng ’10 are the co-authors of the paper “Fidelity in Quasi-1D Systems as a Probe for Anderson Localization,” published in Acta Physica Polonica A, Proceedings of the 4th Workshop on Quantum Chaos and Localisation Phenomena, Warsaw, in 2009. They wrote the paper with Ulrich Kuhl, and Hans-Jürgen Stöckmann, who are collaborators from the University of Marburg.

This publication is part of the conference proceedings for a workshop at the Polish Academy of Sciences in Warsaw where Kottos presented this past summer. The combined theoretical and experimental work done in this project put forward a method for which the celebrated phenomenon of Anderson Localization could be detected through a measure known as Fidelity, which is typically thought of as probing the stability of a system against external perturbations. This work will constitute a large part of Zheng’s senior physics thesis.
