Figure 3

Variations of occupation number w.r.t. β and M are plotted. (a) Variations with β for M = 0 (dashed line) and for M = −0.15 (solid line). Occupation number at central site (N₀, \({N}_{0}^{\text{'}}\)) and rest of the lattice sites (N₁, \({N}_{1}^{\text{'}}\)), respectively. (b) Variation with M for β = 1., where occupation number at central (solid line) and rest of the lattice sites (dashed). Here, all the parameters are in dimensionless units with γ = 1.25, l = 1.84, p = 0, G = −1, m = 1 and t = 1.
