Self-avoiding trails in two and three dimensions
Xiaodi Su, Zongzheng Zhou, Qianqian Wu
The self-avoiding trail is an important variant of the self-avoiding walk. In this work, we employ an irreversible Markov chain Monte Carlo algorithm, together with the reversible…
The rate of convergence of the critical mean-field O(N) magnetization via multivariate nonnormal Stein's method
Timothy M. Garoni, Aram Perez, Zongzheng Zhou
We study the distribution of the magnetization of the critical mean-field O(N) model with N > 1. Specifically, we bound the Wasserstein distance between the finite-volume and limit…
Correction-to-scaling exponent for percolation and the Fortuin--Kasteleyn Potts model in two dimensions
Yihao Xu, Tao Chen, Zongzheng Zhou +2
The number of clusters (per site) of size , a central quantity in percolation theory, displays at criticality an algebraic scaling behavior of the form $n_s\simeq s^{-τ}\,…
Logarithmic Finite-Size Scaling of the Four-Dimensional Ising Model
Zhiyi Li, Tianning Xiao, Zongzheng Zhou +2
Field-theoretical calculations predict that, at the upper critical dimension , the finite-size scaling (FSS) behaviors of the Ising model would be modified by multiplicative…
Finite-Size Scaling of the High-Dimensional Ising Model in the Loop Representation
Tianning Xiao, Zhiyi Li, Zongzheng Zhou +2
Besides its original spin representation, the Ising model is known to have the Fortuin-Kasteleyn (FK) bond and loop representations, of which the former was recently shown to exhib…
Interplay of the complete-graph and Gaussian fixed-point asymptotics in finite-size scaling of percolation above the upper critical dimension
Mingzhong Lu, Sheng Fang, Zongzheng Zhou +1
Percolation has two mean-field theories, the Gaussian fixed point (GFP) and the Landau mean-field theory or the complete graph (CG) asymptotics. By large-scale Monte Carlo simulati…
Simulation of IBM's kicked Ising experiment with Projected Entangled Pair Operator
Hai-Jun Liao, Kang Wang, Zong-Sheng Zhou +2
We perform classical simulations of the 127-qubit kicked Ising model, which was recently emulated using a quantum circuit with error mitigation [Nature 618, 500 (2023)]. Our approa…
Geometric properties of the complete-graph Ising model in the loop representation
Zhiyi Li, ZongZheng Zhou, Sheng Fang +1
The exact solution of the Ising model on the complete graph (CG) provides an important, though mean-field, insight for the theory of continuous phase transitions. Besides the origi…
Geometric scaling behaviors of the Fortuin-Kasteleyn Ising model in high dimensions
Sheng Fang, Zongzheng Zhou, Youjin Deng
Recently, we argued [Chin. Phys. Lett. , 080502 (2022)] that the Ising model simultaneously exhibits two upper critical dimensions in the Fortuin-Kasteleyn (FK…
Unwrapped two-point functions on high-dimensional tori
Youjin Deng, Timothy M. Garoni, Jens Grimm +1
We study unwrapped two-point functions for the Ising model, the self-avoiding walk and a random-length loop-erased random walk on high-dimensional lattices with periodic boundary c…
Logarithmic finite-size scaling of the self-avoiding walk at four dimensions

The -vector spin model, which includes the self-avoiding walk (SAW) as a special case for the limit, has an upper critical dimensionality at four spatial dime…
Percolation effects in the Fortuin-Kasteleyn Ising model on the complete graph
Sheng Fang, Zongzheng Zhou, Youjin Deng
The Fortuin-Kasteleyn (FK) random cluster model, which can be exactly mapped from the -state Potts spin model, is a correlated bond percolation model. By extensive Monte Carlo s…

We study the variable-length ensemble of self-avoiding walks on the complete graph. We obtain the leading order asymptotics of the mean and variance of the walk length, as the numb…
Random-length Random Walks and Finite-size scaling in high dimensions

We address a long-standing debate regarding the finite-size scaling of the Ising model in high dimensions, by introducing a random-length random walk model, which we then study rig…
Geometric explanation of anomalous finite-size scaling in high dimensions
Jens Grimm, Eren Metin Elçi, Zongzheng Zhou +2
We give an intuitive geometric explanation for the apparent breakdown of standard finite-size scaling in systems with periodic boundaries above the upper critical dimension. The Is…
Leaf-excluded percolation in two and three dimensions
Zongzheng Zhou, Xiao Xu, Timothy M. Garoni +1
We introduce the \emph{leaf-excluded} percolation model, which corresponds to independent bond percolation conditioned on the absence of leaves (vertices of degree one). We study t…
