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.

Un segno contro la violenza di genere – 26 novembre ore 13.00

in

Nel Novembre dello scorso anno ci siamo incontrate e incontrati per ricordare insieme, rumorosamente, il femminicidio di Giulia Cecchettin. L’iniziativa è nata spontaneamente per rispondere allo smarrimento di tante di noi, toccate dalla vicinanza dell’esperienza di Giulia, studentessa universitaria (peraltro, in ambito scientifico) come noi siamo state o siamo. È servita però anche ad aprire una discussione sul tema della violenza di genere all’interno agli spazi che viviamo quotidianamente, come lavoratrici e studentesse del dipartimento e degli enti di ricerca che vi sono ospitati.

ISC researchers L. Pilozzi and V. Brosco write on a recent experiment [1] with photonic waveguides  which demonstrates the connection between non-Abelian holonomies and adiabatic particle transport, paving the way to the geometric and topological control of light trajectories.

The experiment by Sun and colleagues represents one of the few observations so far of the non-Abelian Wilczek–Zee holonomy. But by employing Thouless pumping as a tool for probing non-Abelian topological physics, it also paves the way for the geometric control of photon states and light trajectories in real space — a fundamental step in the direction of photonic information processing [2].… Read the rest

There is only one time

We draw a picture of physical systems that allows us to recognize what “time” is by requiring consistency with the way that time enters the fundamental laws of Physics. Elements of the picture are two non-interacting and yet entangled quantum systems, one of which acting as a clock. In this setting, employing the Page and Wootters mechanism with tools from large-N quantum approaches, we show that there is not a “quantum time”, possibly opposed to a “classical” one; there is only one time, and it is a manifestation of entanglement.… Read the rest
