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…

Role of the transverse field in inverse freezing in the fermionic Ising spin-glass model
S. G. Magalhaes, C. V. Morais, F. M. Zimmer
We investigate the inverse freezing in the fermionic Ising spin-glass (FISG) model in a transverse field . The grand canonical potential is calculated in the static approximatio…
