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…

Modulated replica symmetry breaking schemes for antiferromagnetic spin glasses
R. Oppermann, D. Sherrington, M. Kiselev
We define modulated replica symmetry breaking (RSB)-schemes which combine tree- and wave-like structures. A modulated scheme and unmodulated RSB are applied at 1-step level to a se…
