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…
Spectral Signatures of Third-Order Pseudo-Transitions in Finite Systems: An Eigen-Microstate Approach
Wei Liu, Songzhi Lv, Xin Zhang +3
Third-order pseudo-transitions in finite systems reflect reorganization beyond conventional criticality, yet their identification usually relies on microcanonical entropy, which is…
Pseudo Transitions in the Finite-Size Blume-Capel Model
Lei Shi, Wei Liu, Xiang Li +4
This article investigates the pseudo transitions of the Blume-Capel model on two-dimensional finite-size lattices. By employing the Wang-Landau sampling method and microcanonical i…
Geometric properties of the additional third-order transitions in the two-dimensional Potts model
Wei Liu, Xin Zhang, Lei Shi +4
Within the canonical ensemble framework, this paper investigates the presence of higher-order transition signals in the -state Potts model (for ), using two geometric…
