Georg Maret

from Wikipedia, the free encyclopedia

Georg Maret (* 1949 in Trier ) is a German experimental solid-state physicist.

Maret studied at the University of Bonn and the Technical University of Munich and received her doctorate at the high magnetic field laboratory of the CNRS and the Max Planck Society in Grenoble under Klaus Dransfeld . He then carried out research at the high field laboratory in Grenoble until 1993. He was director of the Charles Sadron Institute for Polymer Research at the CNRS in Strasbourg and has been Professor of Experimental Physics at the University of Konstanz since 1997 . From 2000 to 2003 he headed the University's Optics Center and from 2001 to 2010 he was the spokesperson for the Graduate School Soft Condensed Matter Physics of Model Systems (Universities of Grenoble, Strasbourg, Constance). Maret was Dean of the Faculty of Mathematics and Natural Sciences from 1999 to 2003 and from 2006 spokesman for the Physics department.

He developed the method of diffusing wave spectroscopy , which examines interferences in multiply scattered light and is used in particular to examine soft matter (such as colloids , polymers, biological macromolecules). Maret used it to study melting and crystallization phenomena of colloids in two dimensions.

In 2000, his laboratory at the University of Konstanz received one of the strongest magnets in the world at the time, which generated fields up to 400,000 times the earth's magnetic field. In Konstanz, the magnet was used, among other things, to investigate the crystallization of polymers in weightlessness (which can be simulated in the strong fields generated due to the diamagnetism of ordinary matter).

In May 2011 he received one of the Reinhart Koselleck funding projects of the DFG, endowed with 1.2 million euros, to research the magnetic sense of orientation of living beings such as pigeons. To this end, he plans to use his Diffusing Wave Spectroscopy on infrared scattered light in the brain and body tissue of pigeons in order to examine its reaction to magnetic fields and first of all to determine which parts of the body play a role in this. In the case of pigeons, for example, magnetic particles in the beak or magnetically sensitive chemical reactions in the eye were discussed.

In 2011 he received the Gentner-Kastler-Prize . In 2003 he was a Loeb Lecturer at Harvard University . In 1993 he received the Prix Leconte of the Académie des Sciences .
