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 |
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.

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.
