Paper on nonergodic quantum engines appeared on Nature Communications!
25/11/2025
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)
ERC StG awarded!
4/9/2025
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.
New Preprint on: Observing Bethe strings in an attractive Bose gas far from equilibrium!
15/5/2025
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.
New Preprint on: Observation of a generalized Gibbs ensemble in photonics!
17/3/2025
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!
A. Bastianello, A. Tikan, F. Copie, S. Randoux, P. Suret, arXiv:2503.16526
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!
