Chair of Computational Condensed Matter Theory

Condensed matter comprises more or less everything we see. To a very large extent, its properties result from the interplay of quantum mechanics and the Coulomb interaction between nuclei and electrons. This interplay keeps producing stunning phenomena many of which are still to be understood. To achieve this understanding is the goal we are striving at using predominantly computational means. Our current emphasis is on transport and dynamics; recent research topics include:


  Ultrafast Dynamics     Quantum Critical Phenomena     Molecular Electronics



Brigitta and Oskar Braumandl prize for Max Graml

Congratulations to Max Graml for receiving the research prize of the Brigitta and Oskar Braumandl Foundation! The award recognizes Max's outstanding contributions to advancing our understanding of high-harmonic spectra. The prize has been awarded during a ceremony in the historic city hall by Gertrud Maltz-Schwarzfischer, Mayor of Regensburg.

Funding within the Emmy Noether Programme

The German Research Foundation funds the proposal "Real-time quantum simulations of ultrafast exciton dynamics with atomic resolution" by Jan Wilhelm! With the funding, he will establish an independent junior research group at the University of Regensburg.


Highly conductive single-molecule topological insulators

Researchers in Prof. Venkataraman's group (Columbia University, New York) have built organic topological-insulator wires, which show an unusual increase in conductance for longer wires. Our theoretical models support an interpretation of these results based on topology.

Chirality-induced spin selectivity (CISS) - progess and challenges

We review the theory of the CISS effect, that is, phenomena in which the chirality of molecular species imparts significant spin selectivity to various electron processes. We discuss CISS effects in electron transmission, electron transport, and chemical reactions.

Atomically resolved single-molecule triplet quenching

Led by Prof. Repp and Prof. Lupton (both UR), an experimental breakthrough has been achieved in measuring the energy transfer between a single oxygen molecule and a dye molecule. While first theoretical steps have been taken with success, a detailed understanding is yet to be worked out.
