چکیده
The Yang-Lee zeros of the Q-state Potts model on recursive lattices are studied for noninteger values of Q. Considering one-dimensional (1D) lattice as a Bethe lattice with coordination number equal to 2, the location of Yang-Lee zeros of 1D ferromagnetic and antiferromagnetic Potts models is completely analyzed in terms of neutral periodical points. Three different regimes for Yang-Lee zeros are found for Q>1 and 01. Complex magnetic field metastability regions are studied for the Q>1 and 0<Q<1 cases. The Yang-Lee edge singularity exponents are calculated for both 1D and Bethe lattice Potts models. The dynamics of metastability regions for different values of Q is studied numerically.

Exact results for the zeros of the partition function of the Potts model on finite lattices
The Yang-Lee zeros of the Q-state Potts model are investigated in 1, 2 and 3 dimensions. Analytical results derived from the transfer matrix for the one-dimensional model reveal a systematic behavior of the locus of zeros as a function of Q. For 1 < Q < 2 the zeros in the complex x = exp(βHq) plane lie inside the unit circle, while for Q > 2 they lie outside the unit circle for finite temperatu...
متن کاملPartition function zeros of the one - dimensional Potts model : The recursive method
The Yang-Lee, Fisher and Potts zeros of the one-dimensional Q-state Potts model are studied using the theory of dynamical systems. An exact recurrence relation for the partition function is derived. It is shown that zeros of the partition function may be associated with neutral fixed points of the recurrence relation. Further, a general equation for zeros of the partition function is found and ...
متن کاملYang-Lee zeros of the two- and three-state Potts model defined on phi3 Feynman diagrams.
We present both analytical and numerical results on the position of partition function zeros on the complex magnetic field plane of the q=2 state (Ising) and the q=3 state Potts model defined on phi(3) Feynman diagrams (thin random graphs). Our analytic results are based on the ideas of destructive interference of coexisting phases and low temperature expansions. For the case of the Ising model...
متن کاملYang-Lee zeros of the Q-state Potts model in the complex magnetic-field plane
The microcanonical transfer matrix is used to study the distribution of YangLee zeros of the Q-state Potts model in the complex magnetic-field (x = eβh) plane for the first time. Finite size scaling suggests that at (and below) the critical temperature the zeros lie close to, but not on, the unit circle with the two exceptions of the critical point x = 1 (h = 0) itself and the zeros in the limi...
متن کاملPartition Function Zeros of the Q-state Potts Model for Non-integer Q
The distribution of the zeros of the partition function in the complex temperature plane (Fisher zeros) of the two-dimensional Q-state Potts model is studied for non-integer Q. On L × L self-dual lattices studied (L ≤ 8), no Fisher zero lies on the unit circle p0 = e iθ in the complex p = (e − 1)/√Q plane for Q < 1, while some of the Fisher zeros lie on the unit circle for Q > 1 and the number ...
