Hi, I am Alvise Bastianello! Welcome to my personal webpage.
I am a theoretical physicist working on quantum and classical systems far from equilibrium in strongly interacting regimes. I like to use analytical techniques to study this interesting problem, and forge along the way novel methods relevant for experiments.

Forthcoming conference "Threefold Quantum: Theory, Experiment, Computation Out of Equilibrium" 11th-13th of March 2026 (Paris)
15/1/2026
Together with Stefano Scopa (ENS) and Andrea De Luca (ENS), I am co-organizing a conference targeting quantum many-body systems out of equilibrium.
By gathering experts in analytical theory, numerical and computational methods, and experimental platforms, Threefold Quantum will foster direct exchange and dialogue between communities that often interact only indirectly.
Participants are encouraged to apply for contributed talks and posters!
Forthcoming conference "Exact Hydrodynamics of Integrable systems: mathematics and physics" 9th and 10th of March 2026 (Paris)
3/1/2026
I am co-organizing 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 aims to bring together researchers from physics and mathematics to foster genuine cross-fertilization through intensive, thematically organized sessions.
New Preprints on:
Realization of fractional Fermi seas
Exotic critical states as fractional Fermi seas in the one-dimensional Bose gas
20/2/2026
The Pauli exclusion principle is a cornerstone of quantum physics: in the ground state, fermions occupy the lowest-energy levels forming a Fermi sea. In one-dimension, when interactions are deeply linked to statistics, even interacting bosons feature emergent Fermi seas universally described by the Tomonaga-Luttinger liquid approach. In these partner preprints, we show that generalizations of Fermi seas with a fractional occupancy can be realized in ultracold bosons out of equilibrium!
In this theoretical preprint, we show how fractional Fermi seas can be realized through cyclic changes in the interactions in the 1d Bose gas. Correlation functions in these states feature a new form of criticality, beyond the Tomonaga-Luttinger liquid
As a cherry on top, fractional Fermi seas are realized in practice in ultracold Cesium atoms, and they imprint Friedel oscillations in the one-body correlation function
New Preprint on: Experimental observation of ballistic correlations in integrable turbulence !
31/1/2026
Correlation functions lie at the core of our understanding of many-body phenomena, and in particular unequal-time correlations detect the emergence of hydrodynamics. In contrast with general systems following the Fick law, which behave diffusively, integrable models show ballistic behavior in correlation functions.
In a new preprint, we observe ballistic correlation functions in a photonic platform whose dynamics is well-described by the Nonlinear Schroedinger equation, and compare observations with predictions from GHD.
A special thanks goes to Elias Charnay who collected such great experimental data!
New paper on PRA: Observation of a generalized Gibbs ensemble in photonics!
13/1/2026
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.
