Interdependent Networks: Novel Physical Phase Transitions

Abstract
A framework for studying the percolation theory of interdependent networks will be presented. In interdependent networks, such as infrastructures, when nodes in one network fail, they cause dependent nodes in other networks to also fail.

The Hyperspin Machine in Nature Communications

in ,

Our colleagues Claudio Conti and Marcello Calvanese-Strinati have recently published a beautiful theoretical work showing how coupled parametric oscillators can simulate multidimensional continuous spin models. Read more on Nature Communications, 13 7248 (2022)

Abstract

From condensed matter to quantum chromodynamics, multidimensional spins are a fundamental paradigm, with a pivotal role in combinatorial optimization and machine learning. Machines formed by coupled parametric oscillators can simulate spin models, but only for Ising or low-dimensional spins.

Thouless pumping of light with a twist – Nature Physics News and Views

in ,

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

News and Views on “Thermally reconfigurable random lasers”

in , ,

Light can control microparticles and microstructures can shape light, leading to a wide range of practical applications as well as interesting physics.

By combining optically controlled micro-heaters with thermophilic particles attracted by them researchers form University College London obtained microlasers with programmable and reversible patterns. This achievement is a nice demonstration of what happens when colloidal science meets photonics and is now published in Nature Physics and highlighted by Neda Ghofraniha in News and Views .… Read the rest

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.

“Hyper-auxetic” polymer networks published in Nature Communications

in ,

Andrea Ninarello, José Ruiz-Franco & Emanuela Zaccarelli have published Onset of criticality in hyper-auxetic polymer networks in Nature Communications volume 13, Article number: 527 (2022)

Against common sense, auxetic materials expand or contract perpendicularly when stretched or compressed, respectively, by uniaxial strain, being characterized by a negative Poisson’s ratio ν. The amount of deformation in response to the applied force can be at most equal to the imposed one, so that ν = − 1 is the lowest bound for the mechanical stability of solids, a condition here defined as “hyper-auxeticity”.… Read the rest
