Difetti e sincronizzazione in mezzi oscillatori disomogenei di Massimo Cencini

in , , ,

Massimo Cencini ci parla del problema della sincronizzazione tra oscillatori in presenza di disomogeneità spaziali oggetto di un suo recente lavoro di ricerca. 

 

L’accoppiamento tra oscillatori in sistemi estesi spazialmente tende a bloccare loro frequenza su un valore comune. In presenza di non-omogeneità spaziali, il blocco di regioni diverse a frequenze differenti porta alla parcellizzazione, ovvero a una serie di cluster sincronizzati (detti plateau).

Dinamiche interne riproducibili di Stefano Iubini

in , ,

Stefano Iubini ci segnala un suo lavoro recente sulla dinamica di sistemi non-lineari in presenza di forzanti caotiche, in collaborazione con Università degli Studi di Firenze e Universitaet Postdam.

La risposta di un sistema dinamico nonlineare a un segnale forzante caotico è tipicamente anch’essa una dinamica caotica. Tuttavia si possono incontrare due situazioni distinte:

  1. il sistema segue fedelmente (in modo riproducibile) la forzante esterna, pur essendo la forzante e la risposta entrambe irregolari;
  2. il sistema produce una risposta irregolare ma irriproducibile: una replica del sistema anche solo impercettibilmente perturbata e sottoposta al medesimo segnale evolve in maniera completamente diversa.

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.

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.

Abstract

Pursuing a drifting target in a turbulent flow is an extremely difficult task whenever the searcher has limited propulsion and maneuvering capabilities. Even in the case when the relative distance between pursuer and target stays below the turbulent dissipative scale, the chaotic nature of the trajectory of the target represents a formidable challenge.

Coexistence of Plasmoid and Kelvin–Helmholtz Instabilities in Collisionless Plasma Turbulence published in Astrophysical Journal April 2022

in ,
ISC researchers Dario Borgogno e Daniela Grasso have  recently published the following interesting work,
Abstract
The plasmoid formation in collisionless plasmas, where magnetic reconnection within turbulence may take place
driven by the electron inertia, is analyzed. We find a complex situation in which, due to the presence of strong
velocity shears, the typical plasmoid formation, observed to influence the energy cascade in the
magnetohydrodynamic context, has to coexist with the Kelvin–Helmholtz (KH) instability.

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
