Spin Glass Phase Exists in the Random Weak Disorder for the Villain Model ()
ABSTRACT
In this work we have studied non random Villain model by introducing
simple defects to calculate degeneracies of the first excited states using
Pfaffian approach through a perturbation theory. The distributions of
excitations of the ground states are displayed graphically. The results are
indicated that spin glass occurs in the weak disorder for the Villain model. At
the concentration of defect bonds p=0.03,
the distribution behaves in the same manner as for p=0.5 for different sizes of lattice. The latest result of the spin
glass is presented in this paper.
