Dynamics of an Ising Spin Glass on the Bethe Lattice
Martin Kiemes, Heinz Horner
We study the dynamical low temperature behaviour of the Ising spin glass on the Bethe lattice. Starting from Glauber dynamics we propose a cavity like Ansatz that allows for the tr…
Time Dependent Local Field Distribution and Metastable States in the SK-Spin-Glass
Heinz Horner
Different sets of metastable states can be reached in glassy systems below some transition temperature depending on initial conditions and details of the dynamics. This is investig…
Glassy Dynamics and Aging in Disordered Systems
Heinz Horner
This lecture deals with glassy dynamics and aging in disordered systems. Special emphasis is put on dynamic mean field theory. In the first part I present some of the systems of in…
Low frequency, low temperature properties of the spin-boson problem
Heinz Horner
Low temperature and low frequency properties of a spin-boson model are investigated within a super operator and Liouville space formulation. The leading contributions are identifie…
Non-equilibrium dynamics of simple spherical spin models
W. Zippold, R. Kuehn, H. Horner
We investigate the non-equilibrium dynamics of spherical spin models with two-spin interactions. For the exactly solvable models of the d-dimensional spherical ferromagnet and the…
Neural Networks
Heinz Horner, Reimer Kuehn
We review the theory of neural networks, as it has emerged in the last ten years or so within the physics community, emphasizing questions of biological relevance over those of imp…
Bounds on learning in polynomial time
Heinz Horner, Anthea Bethge
The performance of large neural networks can be judged not only by their storage capacity but also by the time required for learning. A polynomial learning algorithm with learning…
Drift, creep and pinning of a particle in a correlated random potential
Heinz Horner
The motion of a particle in a correlated random potential under the influence of a driving force is investigated in mean field theory. The correlations of the disorder are characte…
