The role of nestedness and saturating feedback in bipartite ecological systems
Nirbhay Patil, Ada Altieri
Large ecosystems balance competition and cooperation, yet standard generalized Lotka--Volterra models make mutualism destabilizing by amplifying disorder and driving unbounded grow…
Dynamical systems on ultra small-world networks
Nirbhay Patil, Ada Altieri, Fabian Aguirre-Lopez
Despite the knowledge that social, economical, and ecological networks are often of a small-world nature with inter-nodal distance growing even slower than logarithmically with sys…
Les Houches lectures on Theoretical Ecology: High-dimensional models and extreme events
Ada Altieri
The study of ecological systems is gaining momentum in modern scientific research, driven by an abundance of empirical data and advancements in bioengineering techniques. However,…
Random motility regulation as a generic mechanism of community formation
Alberto Dinelli, Ada Altieri, Julien Tailleur
The self-organization of microbial ecosystems involves a large variety of mechanisms, ranging from biochemical signaling to population dynamics. Among these, the role of motility r…
Higher-order Ising model on hypergraphs
Thomas Robiglio, Leonardo Di Gaetano, Ada Altieri +2
Non-dyadic higher-order interactions affect collective behavior in various networked dynamical systems. Here we discuss the properties of a novel Ising model with higher-order inte…
Nonreciprocal Spin-Glass Transition and Aging
Giulia Garcia Lorenzana, Ada Altieri, Giulio Biroli +2
Disordered systems generically exhibit aging and a glass transition. Previous studies have long suggested that non-reciprocity tends to destroy glassiness. Here, we show that this…
