Blume-Emery-Griffiths Model in a Random Transverse Field
H. Ez-Zahraouy, H. Mahboub, A. Benyoussef +1
The effect of the random quantum transverse field on the tricritical behavior of the spin-1 Blume- Emery- Griffiths (BEG) model is studied using effective field theory. It is f…
Surface Effects On Wetting and Layering Transitions
H. Ez-Zahraouy, A. Benyoussef, L. Bahmad
Wetting phenomena plays an interesting role in the technological development of materials. Recently, much attention has been directed to the study of magnetic solid films. To under…
Wetting of an Ising system with perfect and corrugated surfaces in a transverse field
L. Bahmad, A. Benyoussef, H. Ez-Zahraouy
Using the mean field theory, a comparative study of the wetting and layering transitions of a spin-1/2 Ising model with perfect and corrugated surfaces, is established. The phase d…
Wetting and layering transitions of a spin-1/2 Ising model in a random transverse field
L. Bahmad, A. Benyoussef, A. El-Kenz +1
The effect of a random transverse field (RTF) on the wetting and layering transitions of a spin-1/2 Ising model, in the presence of bulk and surface fields, is studied within an ef…
Layering transitions of the spin-1/2 Ising model in a transverse magnetic field
L. Bahmad, A. Benyoussef, A. Boubekri +1
Using mean field theory, the effect of the transverse magnetic field on the layering and wetting transitions of the spin-1/2 Ising model with longitudinal magnetic field is studied…
