Werner Hanke (physicist)

Werner Hanke (born July 8, 1943 ) is a German theoretical solid-state physicist .

Hanke studied physics from 1963 at the Ludwig Maximilians University in Munich (diploma in 1969) and received his doctorate in 1972 from the Technical University of Munich . From 1972 to 1974 he was a post-doctoral student with Walter Kohn and Lu Jeu Sham at the University of California, San Diego . From 1975 to 1985 he was C3 professor at the Max Planck Institute for Solid State Research in Stuttgart, completed his habilitation in 1978 in Stuttgart in theoretical physics and became professor at the University of Stuttgart in 1985 . From 1985 until his retirement in 2008 he was a full professor at the Julius Maximilians University of Würzburg . From 2002 to 2004 he was Dean of the Faculty of Physics and Astrophysics. He has a research professorship in Würzburg.

He deals with quantum mechanical many-particle physics in solids, strongly correlated electron systems, high-temperature superconductivity , topological insulators ( quantum spin Hall effect ) and magnetism . He works in particular with the functional renormalization group (multi-orbit variant), which makes it possible to overcome the typical differences in the size scales of energy (eV of the fundamental interactions of electrons and ions, meV for the differences in the phases), for example in high-temperature superconductors there superconductor and antiferromagnetic phases).

In 2015, he and others proposed a search for materials for topological superconductors in which supercomputer calculations based on the functional renormalization group are combined with scanning tunneling microscopy .

In 2016, he and colleagues proposed a material (bismuth layer on silicon carbide) that, due to the larger energy gap, enables topological insulators (quantum spin Hall materials) to be possible at room temperature. The quantum spin Hall effect is a promising effect for spintronics and was experimentally demonstrated for the first time simultaneously with the first topological insulator in 2007 by the group of Laurens Molenkamp (University of Würzburg).

As a visiting scientist, he led the first solid-state research program at the Kavli Institute for Theoretical Physics (KITP) in Santa Barbara in 1980/81 (under the then director Walter Kohn , and later several times visiting professor), in 1981 he was visiting professor at Yale University and Marie-Curie - Visiting Professor at the University of Paris , 1997 Visiting Professor at Florida State University in Tallahassee, where he worked with John Robert Schrieffer , and 1999/2000 McCullough Visiting Professor at Stanford University , where he worked with Shoucheng Zhang . In 2002 he was visiting professor at the University of Tokyo .

In 2016 he was awarded an honorary doctorate at TU Graz and in 2011 a fellow of the American Physical Society . Since 2003 he has been a member of the Computer Science Commission of the Bavarian Academy of Sciences. Since 1994 he has been on the council of supercomputing centers in Stuttgart and Munich .
