We study the site-bond percolation problem for clusters of holes and particles with antiferromagnetic order by means of the Bethe cluster approximation. We find that the droplets (i.e. P B =1- e -| K|/2) diverge at the antiferromagnetic critical point H=0, T= T c; however for H≠0 they diverge along a percolation line which is different from the Antiferromagnetic Phase Boundary except at T=0.

Abstract
We study the site-bond percolation problem for clusters of holes and particles with antiferromagnetic order by means of the Bethe cluster approximation. We find that the droplets (i.e. P B =1- e -| K|/2) diverge at the antiferromagnetic critical point H=0, T= T c; however for H≠0 they diverge along a percolation line which is different from the Antiferromagnetic Phase Boundary except at T=0.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
