On the Yang–Lee edge singularity for Ising model on nonhomogeneous structures
چکیده انگلیسی

We studied distribution of zeros of the partition function of ferromagnetic Ising model near the Yang–Lee edge on two self-similar structures. We have shown that the nature of associated critical behavior crucially depends on the local lattice structure: If the sites of higher coordination number make an infinite connected cluster then we find an usual power-law behavior, while a logarithmic divergence of the correlation length develops near the edge in the case that these sites make only finite islands. We reveal also a close connection between Yang–Lee edge critical behavior and critical behavior of a simple zero-field Gaussian model on the same structures.
