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…
Higher-order interactions in ecology can be hidden in plain sight
Violeta Calleja-Solanas, Santiago Lamata-Otín, Carlos Gómez-Ambrosi +2
Higher-order interactions are increasingly recognized as a key component of ecological dynamics. However, we show that higher-order Lotka-Volterra dynamics can, in some scenarios,…
Cross-order induced behaviors in contagion dynamics on higher-order networks
Kaloyan Danovski, Sandro Meloni, Michele Starnini
Recent studies have shown that novel collective behaviors emerge in complex systems due to higher-order interactions. However, the way in which the structural correlations of these…
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…
Towards a less spherical cow: Species differences dilute the stabilizing effect of higher-order interactions
Marc Duran-Sala, Sandro Meloni, Violeta Calleja-Solanas
Ecological models traditionally explain stability and coexistence through pairwise interactions among species. However, interactions can also involve groups of three or more specie…
