Higher-order contagion processes in 3.99 dimensions
Sandro Meloni, Andrea Gabrielli, Pablo Villegas
Higher-order interactions have recently emerged as a promising framework for describing new dynamical phenomena in heterogeneous contagion processes. However, a fundamental open qu…
Chladni states in Ising Spin Lattices
Giulio Iannelli, Pablo Villegas
Low-temperature spin dynamics can become trapped in long-lived patterns shaped by the geometry of the interaction network. Here we introduce Chladni states: spin configurations obt…
The Synergistic Route to Stretched Criticality
Lorenzo Lucarini, Sandro Meloni, Pablo Villegas
Griffiths phases are typically associated with quenched disorder, while frustration gives rise to multistability and spin-glass behavior. Whether extended criticality can arise in…
Structural coarse-graining enables noise-robust functional connectivity and reveals hidden inter-subject variability
Izaro Fernandez-Iriondo, Antonio Jimenez-Marin, Jesus Cortes +1
Functional connectivity estimates are highly sensitive to analysis choices and can be dominated by noise when the number of sampled time points is small relative to network dimensi…
Topological Symmetry Breaking in Antagonistic Dynamics
Giulio Iannelli, Pablo Villegas, Tommaso Gili +1
A dynamic concordia discors, a finely tuned equilibrium between opposing forces, is hypothesized to drive historical transformations. Similarly, a precise interplay of excitation a…
Geometric Criticality in Scale-Invariant Networks
Lorenzo Lucarini, Giulio Cimini, Pablo Villegas
Dimension in physical systems determines universal properties at criticality. Yet, the impact of structural perturbations on dimensionality remains largely unexplored. Here, we cha…
