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…

Crossover component in non critical dissipative sandpile models
A. Benyoussef, M. Khfifi, M. Loulidi
The effect of bulk dissipation on non critical sandpile models is studied using both multifractal and finite size scaling analyses. We show numerically that the local limited (LL)…
