Entropy of the model with different temperature and external magnetic field
Scaling behavior near the critical point Grand canonical ensemble 0,Hc2=-|1l, when u<-h the system is the vacuum state when-h]<u<o and h>0(h<0), it is the fully upper (lower) polarized state: when u>0, it is the partially polarized state Near critical point, density of particle number satisfies scaling law n(u,h, T)-no(u, h,T)=T d/z+1-1/Uz 多 where d/z+1-1/vz=1/2, 1/vz=l, and g(x)=F-1/2[(u uc)/T1/(2T), dimension d=l, critical exponent z=2 and correlation length exponent v=1/2
Scaling behavior near the critical point Grand canonical ensemble Near critical point, density of particle number satisfies scaling law when u<-|h|, the system is the vacuum state; when -|h|<u<0 and h>0 (h<0), it is the fully upper (lower) polarized state; when u>0, it is the partially polarized state
