Alois Loidl

from Wikipedia, the free encyclopedia

Alois Loidl (born April 6, 1945 in Ebensee , Upper Austria) is an Austrian physicist and has been a professor at the University of Augsburg since 1996 .

Life

Loidl studied technical physics at the Vienna University of Technology. After graduation with a degree in engineering (1971), he worked at the Institute of Nuclear Physics at the University of Frankfurt / M . From there, after completing his doctorate (1976), he moved to the University of Mainz , where he completed his habilitation in 1981.

During his time in Mainz, Loidl was a founding member of two DFG Collaborative Research Centers - in some cases also as a spokesperson - and at times chairman of the Institute for Physics.

After two rejected calls to the universities of Missouri-Columbia and Hanover, he followed a third in 1991 to a chair at the Institute for Physics at the TH Darmstadt . In 1994 Loidl completed a research stay at the Chemistry Department of the University of Arizona (Tempe / Phoenix), in the same year he became the first speaker of the Collaborative Research Center 252 (until 1996) and from 1995 he was the managing director of the Institute for Solid State Physics at the TH Darmstadt.

In 1996 Loidl was appointed to the Chair of Experimental Physics V - one of the three newly established chairs of the Augsburg physics focus "Electronic Correlations and Magnetism". Before he was elected to the management committee of the University of Augsburg as Vice-Rector for University Planning for the first time in 2003 , he was a. a. Dean and Senator of the Faculty of Mathematics and Natural Sciences and Environment Officer of the Senate. Loidl held four two-year terms as Vice President or Vice President before he headed the University of Augsburg as permanent representative of the President from August 2010 to September 2011. As such, he also promoted the Augsburg Innovation Park project . In addition, the establishment of an eighth faculty for engineering was one of his stated goals. From 2008 to 2013 Loidl was "Editor in Chief" of the European Physical Journal B. Since May 2012, Alois Loidl has been spokesman for the DFG Collaborative Research Center Transregio 80 "From Electronic Correlations to Functionality" and since 2015 also spokesman for a DFG-funded Chinese-German cooperation on "Emergent Correlated Materials" with locations in Hangzhou, Beijing, Frankfurt am Main and Augsburg.

research

Loidl's research covers a wide range of areas of condensed matter physics. In his working group, various methods of spectroscopy on condensed matter are used, in particular neutron scattering , electron and nuclear magnetic resonance , broadband dielectric spectroscopy , as well as terahertz and infrared spectroscopy .

The research topics that Loidl and his team at the Chair of Experimental Physics V concentrate on are in the areas of electronic correlations and magnetism, physics of the glass transition , new electronic materials for future applications, and biological physics .

His most important works concern:

  • The relaxation dynamics of supercooled liquids, plastic crystals and orientation glasses. The application of dielectric spectroscopy in an unusually broad frequency range of almost 20 decades allowed a detailed characterization of the multitude of dynamic processes in glass-forming matter. These are schematically sketched in the so-called Lunkenheimer-Loidl plot.
  • Spectroscopy of electronically highly correlated matter, especially systems with colossal magnetoresistance , high-temperature superconductors , frustrated magnets, multiferroics or skyrmion crystals. Electromagnons, a new class of excitations in multiferroic materials, were discovered for the first time in his group.
  • In recent times Loidl has been working in interdisciplinary work together with resource strategists and economists increasingly on the development of resource-efficient materials for tomorrow's technologies.

Fonts

Alois Loidl has so far (as of January 2016) published a total of approx. 700 publications in refereed international science journals and books, including approx. 200 articles on Physical Review (mainly B and E) and approx. 60 articles on Physical Review Letters . His work has been quoted more than 16,000 times and his h-index of 65. A complete list of publications can be found at the ORCID 0000-0002-5579-0746.
