What? — Topics of Current Research

Low-Dimensional Spin Systems

Spin excitations in antiferromagnets: from 1 to 2 dimensions – from spinons to spin waves

Interfaces in Correlated Electronic Systems

How do electrons tunnel through grain boundaries of high-Tc cuprates?

Scanning Probe Microscopy

Can the local properties (charge, spin, orbitals) of surfaces be tested, and is our understanding of these degrees of freedom adequate?

Quantum Fluids

Nonlinear response in fermionic superfluids and superconductors: a tool to investigate collective excitations


Double exchange and orbital excitations, formation of polarons and reentrant charge ordering: a playground for cooperative phenomena
Functional Integrals in Condensed Matter Physics
Formalisms, capable to investigate microscopic models beyond perturbation theory
