Synchronization, Kinematic Waves and Spike-Phase-Separation in Feedback Ising Neural Networks on Heterogeneous Graphs
Anna Poggialini, Irem Topal, Fabrizio Lombardi +1
The paper analyzes how structural heterogeneity in neural networks influences collective dynamics, showing that degree variability can trigger synchronized oscillations via a Hopf…
From Exponential to Gaussian Tails: Fractal Wavefront Scaling and the -Weibull Distribution at Phase Transitions
O. V. Pavlovsky, M. Yu. Satleikin
The paper studies how a stochastic cellular‑automaton model of an active medium behaves near a phase transition, showing two distinct activity regimes whose fractal dimensions and…
Nonclassical condensation pathways revealed by the multivariable theory of nucleation
Yijian Wu, Thomas Philippe
The paper extends classical nucleation theory by treating cluster size, density, and interfacial width as independent variables using dynamical density functional theory, revealing…
Generalized Kazakov-Migdal Models on Graphs via Artin-Ihara -function and Random Partitions
So Matsuura, Kazutoshi Ohta
The authors formulate Kazakov‑Migdal gauge theories on arbitrary graphs via the Artin‑Ihara L‑function, recast the cycle‑graph case as a random‑partition model with the Schur measu…
Tilt-driven ferrielectricity in PbZrO
Huazhang Zhang, Ying Liu, Carson Carroll +6
The paper demonstrates that adding an octahedral tilt to the antiferroelectric PbZrO₃ structure breaks symmetry and creates a ferrielectric polar phase, confirmed by first‑principl…
Phase transitions and microphases in elastomers. I. Emergence of stable domains
Manu Mannattil, Haim Diamant, David Andelman
The paper explains how microphase separation in swollen elastomers arises from a mismatch between elastic and thermodynamic length scales, using conventional elasticity theory with…
