Anderson Transitions and Quantum Criticality in Novel Materials: Topological Insulators, Graphene and Friends

Electronic wavefunction near a Quantum Hall transition exhibiting multifractal amplitude fluctuations.

Disorder of some kind is a ubiquitous encounter in any macroscopic solid. From the fundamental point of view it creates novel material classes where interference, quantum phase transitions and the physics of rare events dominate the phase diagrams.

Molecular Electronics

Typical setup of a molecular transport experiment

Molecules represent classes of quantum dots that exhibit unique properties. A profound fundamental interest is especially in molecular systems close to instabilities, because the latter tend to leave a pronounced effects on the transport characteristics.

Molecular Materials and Their Cooperative Phenomena

Graphene flake with zigzag termination and buckling.

Molecular Materials comprise a broad class of solids including graphene, supramolecular structures and hypothetical metamaterials. Their cooperative properties are rich, tunable and can often be obtained quantitatively with sophisticated ab intio methods.
