Spin precession in disordered systems: Anomalous relaxation due to heavy tailed field distributions
Falk Scheffler, Philipp Maass
We investigate spin precession in the presence of randomly distributed field sources. Their fields h_i reorient by thermally activated transitions and decrease as r^{-mu} with the…

Exact Density Functionals in One Dimension
Joachim Buschle, Philipp Maass, Wolfgang Dieterich
We propose a new and general method for deriving exact density functionals in one dimension for lattice gases with finite-range pairwise interactions. Corresponding continuum funct…
