Threshold-Controlled Geometric Reorganization in 2D Bootstrap Percolation
Fangfang Wang, Wei Liu, Kai Qi +2
Two-dimensional bootstrap percolation is usually characterized by bulk observables, but whether increasing the activation threshold qualitatively reorganizes the geometry of the ab…

Third-order transitions in Ising and Potts models on Watts--Strogatz small-world networks
Fangfang Wang, Wei Liu, Ke Zhang +4
We study third-order transitions in the two-dimensional Ising and Potts model on regular lattices and Watts--Strogatz small-world networks. Cluster observables are used to track po…

Canonical Criterion for Third-Order Transitions
Fangfang Wang, Wei Liu, Kai Qi +3
Microcanonical inflection-point analysis (MIPA) identifies third-order transitions from derivatives of the microcanonical entropy, but whether such transitions admit a direct canon…
