Andrea Tononi
I am a theoretical physicist doing research on ultracold atomic gases.
My main research interest is understanding the role of geometry in quantum systems confined in curved setups.
I contributed to the study of a Bose gas confined on the surface of a sphere by characterizing its quantum statistical, superfluid and few-body properties, and I addressed the few-body binding problem in mass-imbalanced fermionic mixtures.
Currently, I am a postdoc in the group of Prof. Maciej Lewenstein at ICFO, where I am working within the framework of the PASQuanS2 project.
I previously did 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.
