The research performed by Dr. Jansen is best characterized as computational
solid state physics. The calculations in his group focus on the electronic
structure of solids and the electronic contribution to the total energy of
solids. This work relies on very precise numerical techniques for simple
solids with a small number of atoms in the unit cell, but also semi-empirical
techniques for large systems including defects of surfaces. The numerical
results are used for studies of structural properties and magnetic properties
of solids. These total energy calculations can also yield predictions for
phonon spectra. A parametrized form of the total energy is an essential part
of the molecular dynamics calculations which are performed to explore the
behavior of solids at higher temperatures. Most of the initial program
development and computing is done on local workstations.
Not all work is computer related, however, and part of the research pertains
to details of the basic theory describing the interacting electrons in a solid.

A fun paper, which unfortunately did not contain enough new
information. Numerical errors

The following is a long paper that is too long for
Phys Rev. It contains much of Guenter Schneider's work.
Since I see no better place, it is available on the web:
The Role of Numerical Precision in Calculating the Magnetic Anisotropy
Energy in Density Functional Theory
