The Hyperspin Machine in Nature Communications

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)


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

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

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

ISC researchers Dario Borgogno e Daniela Grasso have  recently published the following interesting work,
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
