Logarithmic scaling correction in quench dynamics of the J1-J2 Potts model
Kun Li, Wanzhou Zhang
In conventional quench dynamics governed by the Kibble-Zurek mechanism (KZM), the defect density generally decays as a pure power law of the quench rate. However, the KZM scaling o…
Local supersolid in moiré modulated Bose-Hubbard model using density-matrix renormalization group method
Siyu Xie, Qiang Xu, Qianqian Shi +1
The search and characterization of supersolid phases remain a central topic in condensed matter physics. Inspired by the experimental discovery of local superfluid and insulating p…
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…
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,…
Tensor network Monte Carlo simulations for the two-dimensional random-bond Ising model
Tao Chen, Erdong Guo, Wanzhou Zhang +2
Disordered lattice spin systems are crucial in both theoretical and applied physics. However, understanding their properties poses significant challenges for Monte Carlo simulation…
