Completely packed O() loop models and their relation with exactly solved coloring models
Yougang Wang, Wenan Guo, Henk W. J. Blöte
We explore the physical properties of the completely packed O() loop model on the square lattice, and its generalization to an Eulerian graph model, which follows by including c…
Reentrance of Berezinskii-Kosterlitz-Thouless-like transitions in three-state Potts antiferromagnetic thin film
Chengxiang Ding, Wenan Guo, Youjin Deng
Using Monte Carlo simulations and finite-size scaling, we study three-state Potts antiferromagnet on layered square lattice with two and four layers and . As temperature…
Efficient algortihms for the two dimensional Ising model with a surface field
Xintian Wu
Bond propagation and site propagation algorithm are extended to the two dimensional Ising model with a surface field. With these algorithms we can calculate the free energy, intern…
Constitutive Relation for Nonlinear Response and Universality of Efficiency at Maximum Power for Tight-Coupling Heat Engines
Shiqi Sheng, Z. C. Tu
We present a unified perspective on nonequilibrium heat engines by generalizing nonlinear irreversible thermodynamics. For tight-coupling heat engines, a generic constitutive relat…
Rényi Information flow in the Ising model with single-spin dynamics
Zhehui Deng, Jinshan Wu, Wenan Guo
The -index Rényi mutual information and transfer entropy for the two-dimensional kinetic Ising model with arbitrary single-spin dynamics in the thermodynamic limit are derived a…
