Andrea Tononi
I am a theoretical physicist specializing in ultracold atomic gases.
My research focuses on understanding the role of geometry in quantum gases confined to curved spaces.
In particular, I contributed to studying a Bose gas on the spherical surface by characterizing its quantum statistical, superfluid and few-body properties.
My broader interests include: low-dimensional atomic mixtures, superfluid hydrodynamics, and quantum information.
Currently, I am a Marie Skłodowska-Curie Postdoctoral Fellow, working on the project QUANTIFLAC under the supervision of Prof. Pietro Massignan in the Barcelona Quantum Monte Carlo group at UPC.
I previously did a postdoc (2023-2025) in the group of Prof. Maciej Lewenstein at ICFO, a postdoc (2021-2023) in the group of Dr. Dmitry Petrov at LPTMS, and the PhD (2018-2021) in the group of Prof. Luca Salasnich at the Università di Padova.
