| contents | Lattice models exhibit significant potential in investigating phase transitions, yet they encounter numerous computational challenges. To address these issues, this study introduces a Monte Carlo-based approach that transforms lattice models into a network model with intricate inter-node correlations. This framework enables a profound analysis of Ising, JQ, and XY models. By decomposing the network into a maximum entropy and a conservative component, under the constraint of detailed balance, this work derive an estimation formula for the temperature-dependent magnetic induction in Ising models. Notably, the critical exponent $β$ in the Ising model aligns well with established results, and the predicted phase transition point in the three-dimensional Ising model exhibits a mere $0.7 \%$ deviation from numerical simulations. |
