Fermionic van Hemmen Spin Glass Model with a Transverse Field
S. G. Magalhaes, F. M. Zimmer, C. V. Morais
In the present work it is studied the fermionic van Hemmen model for the spin glass (SG) with a transverse magnetic field . In this model, the spin operators are written as a bi…

A van Hemmen-Kondo model for disordered strongly correlated electron systems
S. G. Magalhaes, F. M. Zimmer, B. Coqblin
We present here a theoretical model in order to describe the competition between the Kondo effect and the spin glass behavior. The spin glass part of the starting Hamiltonian conta…
