Dynamical solutions of a quantum Heisenberg spin glass model
M. Bechmann, R. Oppermann
We consider quantum-dynamical phenomena in the , infinite-range quantum Heisenberg spin glass. For a fermionic generalization of the model we formulate gene…

Dynamical CPA approach to an itinerant fermionic spin glass model
M. Bechmann, R. Oppermann
We study a fermionic version of the Sherrington-Kirkpatrick model including nearest-neighbor hopping on a -dimensional simple cubic lattices. The problem is reduced to one…
