Klaus Fesser

Klaus Fesser is Professor of Theoretical Physics at the University of Greifswald and is primarily concerned with solid state physics. He was from 1996 to 1998 and from 2002 to 2005 director of the Institute of Physics and has been dean of mathematics and science faculty of the University of Greifswald (as of 2014).

Klaus Fesser in 1979 his doctorate at the University of Cologne ( On the thermodynamics of solitons ) and was then at the Institute for Solid State Research of the Nuclear Research Centre at Jülich. In the early 1980s he was a visiting scientist at Los Alamos National Laboratory. He obtained his habilitation in 1989 at the University of Bayreuth with his work: Investigations on the Electronic Structure of Conducting Polymers ( Studies on the electronic structure of conducting polymers ) and was a professor there, before he was called to Greifswald in 1995.

It deals with low-dimensional solids as quasi- one-dimensional conducting polymers ( and soliton and polaron excitations in these ), Nonlinear dynamics in plasmas, bifurcation theory and nanotubes. In line with the priorities of the University of Greifswald, where it is traditionally conducted research in plasma physics and is also a branch of the Max Planck Institute for Plasma Physics, he studied alongside solid state physics and plasma physics, but focuses as dean of administrative functions of the University.
