Zeros of the partition function and pseudospinodals in long-range Ising models.

چکیده
The relation between the zeros of the partition function and spinodal critical points in Ising models with long-range interactions is investigated. We find that the spinodal is associated with the zeros of the partition function in four-dimensional complex temperature/magnetic field space. The zeros approach the real temperature/magnetic field plane as the range of interaction increases.

Planar Quasiperiodic Ising Models
We investigate zero-field Ising models on periodic approximants of planar quasiperiodic tilings by means of partition function zeros and high-temperature expansions. These are obtained by employing a determinant expression for the partition function. The partition function zeros in the complex temperature plane yield precise estimates of the critical temperature of the quasiperiodic model. Conc...
متن کاملSome new results on Yang-Lee zeros of the Ising model partition function
We prove that for the Ising model on a lattice of dimensionality d 2 2, the zeros of the partition function 2 in the complex p plane (where ,u = e -2PH) lie on the unit circle j,~l = 1 for a wider range of K,,/ = /3J,,,*t than the range K,,,,, 3 0 assumed in the premise of the Yang-Lee circle theorem. This range includes complex temperatures, and we show that it is lattice-dependent. Our result...
متن کاملZeros of the Partition Function for Higher–Spin 2D Ising Models
We present calculations of the complex-temperature zeros of the partition functions for 2D Ising models on the square lattice with spin s = 1, 3/2, and 2. These give insight into complex-temperature phase diagrams of these models in the thermodynamic limit. Support is adduced for a conjecture that all divergences of the magnetisation occur at endpoints of arcs of zeros protruding into the FM ph...
متن کاملLee-yang Zeros for Substitutional Systems
Qualitative and quantitative information about critical phenomena is provided by the distribution of zeros of the partition function in the complex plane. We apply this idea to Ising models on non-periodic systems based on substitution. In 1D we consider the Thue-Morse chain and show that the magnetic field zeros are filling a Cantor subset of the unit circle, the gaps being related to a genera...
متن کاملYang-Lee Edge Singularity of the Infinite-Range Ising Model
The Ising ferromagnet, consisting of magnetic spins, is the simplest system showing phase transitions and critical phenomena at finite temperatures. The Ising ferromagnet has played a central role in our understanding of phase transitions and critical phenomena. Also, the Ising ferromagnet explains the gas-liquid phase transitions accurately. In particular, the Ising ferromagnet in a nonzero ma...
