Together with Stefano Scopa (ENS) and Andrea De Luca (ENS), I co-organized a conference targeting quantum many-body systems out of equilibrium.

Gathering experts in analytical theory, numerical and computational methods, and experimental platforms, Threefold Quantum fostered direct exchange and dialogue between communities that often interact only indirectly.

I am truly grateful for the large international participation in the event and for the enthusiasm of the participants!

I co-organized a conference on the hydrodynamics of integrable models together with Friedrich Hübner (ENS Paris), Alessandra Iacobucci (Université Paris Dauphine-PSL), Ronan Memin (ENS Paris), Stefano Olla (Université Paris Dauphine-PSL).

This focused workshop aimed to bring together researchers from physics and mathematics to foster genuine cross-fertilization through intensive, thematically organized sessions.

Our joint experimental-theoretical work on Observation of a generalized Gibbs ensemble in photonics is now published  A. Bastianello, A. Tikan, F. Copie, S. RandouxPhys. Rev. A 113, 013514 (2026).

The referral process helped us to substantially improve the presentation. We hope this work will help connect the scientific communities working on non-linear classical media and quantum many-body systems, both experimentally and theoretically, by showing the deep analogies between the two.

My work on quantum engines in collaboration with Alberto Brollo and Adolfo Del Campo recently appeared in Nature Communications. In particular, thank to Alberto Brollo as the young driving force in this project!

Under minimal assumptions, we show that additional conservation laws are beneficial to the efficiency of Otto cycles where the working matter follows prethermal phases of matter, compared to canonical prethermalization, provided the external baths have negative temperatures.

Our work also been selected for an outreach summary on the webpage of the Donostia International Physics Center - EHU (link)

I am thrilled to share I have been awarded the ERC Starting Grant for my project "Nonergodic Hydrodynamics in quantum systems" NonErgHydro!

I am immensely grateful to ERC for its generous funding and to all collaborators and friends who supported my research. 

After many efforts, we managed to excite and observe Bethe strings in a one-dimensional ultracold gas of attractive Cesium atoms! Check it out on arXiv.

The experiment has been performed by the group led by H.C. Nägerl at University of Innsbruck. I am specially thankful to Milena Horvath and Sudipta Dhar, for the exceptional quality of experimental data, and for the long hours on Zoom spent teaching me about the experiment. 

Generalized Gibbs Ensembles (GGE) are non-thermal stationary states featured by integrable models: this concept originated in quantum physics, but it describes emergent statistical properties of integrable classical partial differential equations (PDE) as well!

This experiment observes the emergence of the GGE in a photonic platform, well described by the defocusing Non-Linear Schroedinger equation. Within the "soliton gas" framework, relaxation of NLS has been framed within "integrable turbulence": we show that the ending point of integrable turbulence is nothing but the GGE.

Many more analogies between quantum and classical concepts and experiments will come: stay tuned!
