Algorithmic overlaps as thermodynamic variables: from local to cluster Monte Carlo dynamics in critical phenomena
Ian Pilé, Ian Pilé, Youjin Deng +1
We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Swendsen-Wang and Wolff cl…
Ising models on the hydrogen peroxide and other lattices
Xiaofeng Qian, Youjin Deng, Lev N. Shchur +1
We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dim…
Emergent critical phases of the Ashkin-Teller model on the Union-Jack Lattice
Changzhi Zhao, Wanzhou Zhang, Yuan Huang +2
The Ashkin-Teller (AT) model is a classic spin model in statistical mechanics. For traditional homogeneous lattices like triangular and kagome lattices, even when frustration exist…
Variational Monte Carlo (VMC) with row-update Projected Entangled-Pair States (PEPS) and its applications in quantum spin glasses
Tao Chen, Jing Liu, Yantao Wu +2
Solving the quantum many-body ground state problem remains a central challenge in computational physics. In this context, the Variational Monte Carlo (VMC) framework based on Proje…
Phase transitions and crtical exponents in the six-vertex model on kagome lattices
Wei Zhang, Wanzhou Zhang, Jie Zhang +2
Inspired by the experimental realization of direct kagome spin ice [Yue et al., Nat. Nanotechnol. 19, 1101 (2024)], the theoretical six-vertex model on the kagome lattice is system…
Spiral states, first-order transitions and specific heat multipeak phenomenon in -- Ising model: A Wang-Landau algorithm study
Habib Ullah, Kun Li, Haoyu Lu +2
The classical -- Ising model on the honeycomb lattice is important for understanding frustrated magnetic phenomena in materials such as FePS and BaCoTeO,…
