Antiferromagnetic Ising spin glass competing with BCS pairing interaction in a transverse field
S. G. Magalhaes, F. M. Zimmer, C. J. Kipper +1
The competition among spin glass (SG), antiferromagnetism (AF) and local pairing superconductivity (PAIR) is studied in a two-sublattice fermionic Ising spin glass model with a loc…
Spin Glass and ferromagnetism in disordered Cerium compounds
S. G. Magalhaes, F. M. Zimmer, P. R. Krebs +1
The competition between spin glass, ferromagnetism and Kondo effect is analysed here in a Kondo lattice model with an inter-site random coupling between the localized magn…
One-step replica symmetry breaking solution for fermionic Ising spin glass in a transverse field
F. M. Zimmer, S. G. Magalhaes
The fermionic Ising spin glass models in a transverse field are investigated in a Grassmann path integral formalism. The Parisi's scheme of one-step replica symmetry breaking (RSB)…
Quantum critical point in the spin glass-antiferromagnetism competition in Kondo-lattice systems
S. G. Magalhaes, F. M. Zimmer, B. Coqblin
A theory is proposed to describe the competition among antiferromagnetism (AF), spin glass (SG) and Kondo effect. The model describes two Kondo sublattices with an intrasite Kondo…
