Research Interests
Dr. Hans Lustfeld
1. Problems of fuel cells and batteries:
At present I am working on problems of fuel cells and batteries,
in particular on problems of tomographic diagnostics. Since in
these devices the electric current density is high, magnetotomography
seems to be the appropriate method for diagnostics.
(Cooperation between PGI-1, FH-Aachen, JSC and IEK-3, PGI-8)
Quantum mechanical problems of fuel cells:
I am interested in the quantum mechanical aspects of finding good
electrolytes and catalysts. Without a better fundamental understanding
of the electrolytes and catalysts fuel cells will remain in the
present status, i.e. will remain a niche product.
2. Problems of energy storage using supercaps:
Supercaps have huge dielectric constants and the question arises,
whether or not such devices are appropriate for storing energy.
I am interested in particular in electrolytes of metallic composites.
(Cooperation between PGI-1, FH-Aachen and PGI-7)
3. Work on problems of electronic correlation:
Correlations in electron systems arise from the Coulomb interaction
and from the Pauli principle and are essential to the development
of approximations in density-functional theory (DFT).
Dynamical correlations, in particular, are important for time dependent
DFT. Together with K. Sturm (PGI-1) these are studied using an enhanced
class of diagrams beyond RPA.

4. Problems of an interdisciplinary nature:
I am interested in problems, where mathematical tools and
ideas, well known in solid state physics can be applied. This happens
in particular in problems of the geosphere.
Lectures:
The aim in my lectures at the University of Duisburg-Essen
is, to show students that fundamental research can be very close
to applications. Examples are problems occuring in fuel cells.
In particular quantum mechanical investigations of electrolytes
can have a great technological impact. At present my lectures
concentrate on DFT methods and the physics of transport.
