Response Morphologies of a Canonical Fluctuation Diagnostic Across Ehrenfest Phase Transitions
Fangfang Wang, Wei Liu, Ying Tang +1
Microcanonical inflection-point analysis identifies MIPA-type higher-order transition structures from derivatives of the microcanonical entropy. Until recently, however, there was…
Dynamical Partition Functions of Stochastic Dynamics via Variational Flows
Zequn Lin, Ying Tang
Nonequilibrium thermodynamics is governed by the dynamical partition function, and its computation in high-dimensional continuous-state dynamics is a longstanding challenge. The Fe…
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…
