Research Description

Prof. Paschen served as a Visiting Professor in the Center for Quantum Materials at Rice Univresity from August 2016 to January 2017. While in Houston, she worked with many Rice University professors and students. She also co-organized two scientific workshops and one research symposium for the center. She plans to continue her collabortation with the Rice University Center for Quantum Materials as a Strategic International Partner when she returns to Vienna. 

The Rice Center for Quantum Maerials would like to express our appreciation to Prof. Paschen for her time and contrbutions to the center. 


Silke Bühler-Paschen is an experimental condensed matter physicist, working in the fields of strongly correlated electron systems and thermoelectrics. She graduated in physics from Graz University of Technology in Austria, with an external diploma work at the Paul Scherrer Institute in Switzerland. After her PhD studies at EPFL in Lausanne and a postdoctoral stay at ETH Zurich she moved to Germany, where she joined the Max Planck Institute for Chemical Physics of Solids in Dresden, first as scientific collaborator and then as associate professor. After a visiting professorship at the Nagoya University in Japan she was appointed full professor at the Vienna University of Technology in Austria. She received a C3 professorship from the Excellence Program of the Max Planck Society for the Advancement of Outstanding Female Scientist in 2003 and an ERC Advanced Grant from the European Research Council in 2008. She is APS fellow and leader of various national and international research projects. Her team is active in materials synthesis and characterization, using a large pool of different physical property measurements under multiple extreme conditions – spanning, for instance, 7 orders of magnitude in temperature. Topics of current interest include quantum criticality, heavy fermion systems, Kondo insulators, new topological phases, and thermoelectrics.
