Crisis in Time-Dependent Dynamical Systems on PRL cover

in ,

Interesting work by ISC researcher Simona Olmi  and ISC associate Antonio Politi on PRL cover.

S. Olmi and A. Politi, Crisis in Time-Dependent Dynamical Systems, Phys. Rev. Lett. 134, 147202 (2025)

Abstract

Many dynamical systems operate in a fluctuating environment. However, even in low-dimensional setups, transitions and bifurcations have not yet been fully understood. In this Letter we focus on crises, a sudden flooding of the phase space due to the crossing of the boundary of the basin of attraction.

RIFLESSIONE APERTA DAL DIPARTIMENTO DI FISICA

in

 

 

Siamo addolorate ed arrabbiate per gli ennesimi casi di femminicidio di Ilaria Sula e Sara Campanella che sono emersi la scorsa settimana. Questi fatti avvengono a poco più di un anno di distanza dal femminicidio, così tragicamente simile, di Giulia Cecchettin, che tanto ha scosso l’opinione pubblica. Le parole e la posizione ferma della famiglia di Giulia Cecchettin sono rimaste impresse nella nostra memoria perché hanno fornito a tutte e tutti delle categorie mentali efficaci per comprendere ciò che era successo.… Read the rest
