Numerical methods for quasi-stationary distributions
Sara Oliver-Bonafoux, Javier Aguilar, Tobias Galla +1
In stochastic processes with absorbing states, the quasi-stationary distribution provides valuable insights into the long-term behaviour prior to absorption. In this work, we revis…
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…
Critical behavior of a programmable time-crystal lattice gas
R. Hurtado-Gutiérrez, C. Pérez-Espigares, P. I. Hurtado
Time crystals are many-body systems whose ground state spontaneously breaks time-translation symmetry and thus exhibits long-range spatiotemporal order and robust periodic motion.…
The Limits of Inference in Complex Systems: When Stochastic Models Become Indistinguishable
Javier Aguilar, Miguel A. Muñoz, Sandro Azaele
Robust inference for stochastic dynamical systems is often hampered by sparse sampling and the absence of closed-form likelihoods. We introduce a Monte Carlo path-inference framewo…
Topological protection breakdown: a route to frustrated ferroelectricity
Ludovica Falsi, Pablo Villegas, Tommaso Gili +2
Phases manifesting topological patterns in functional systems, like ferroelectric and ferromagnetic vortex superlattices, can manifest intricate and apparently ungovernable behavio…
