Selforganized 3-band structure of the doped fermionic Ising spin glass
H. Feldmann, R. Oppermann
The fermionic Ising spin glass is analyzed for arbitrary filling and for all temperatures. A selforganized 3-band structure of the model is obtained in the magnetically ordered pha…

Pseudogaps and Charge Band in the Parisi Solution of Insulating and Superconducting Electronic Spin Glasses at Arbitrary Fillings
R. Oppermann, H. Feldmann
We report progress in understanding the fermionic Ising spin glass with arbitrary filling. A crossover from a magnetically disordered single band phase via two intermediate bands j…

Replica symmetry breaking solution for the fermionic Ising spin glass and the Ghatak-Sherrington model
H. Feldmann, R. Oppermann
We solve the fermionic version of the Ising spin glass for arbitrary filling μand temperature T taking into account replica symmetry breaking. Using a simple exact mapping from μto…
