SEMINAR: Quantum simulation of strongly correlated systems with neutral alkaline-earth atoms
Giacomo Cappellini got his Ph.D. degree in Atomic and Molecular Photonics in 2016 at European Laboratory for Nonlinear Spectroscopy (LENS, Florence), followed by a postdoc period at the Department of Physics and Astronomy of the University of Florence. His research activity focused on the quantum simulation of interacting systems with SU(N) interaction symmetry and synthetic gauge fields with ultracold gases of two-electron atoms, and on the study of their collisional properties when excited to metastable electronic states. He also developed a strong expertise in the field of optical clock techniques, including high-precision spectroscopy, ultranarrow linewidth laser systems, optical frequency combs and optical fiber links.
In 2019 he worked as a researcher at the Italian National Metrology Institute (INRIM, Turin) on the development of a new generation of optical lattice clock in the UV frequency region.
Since December 2019, G.C. is a permanent researcher at the National Institute of Optics of the National Research Council (CNR-INO). His activity is focused on the development of a new experimental platform based on programmable arrays of individual atoms and on the quantum simulation of strongly interacting systems with two-electron atoms.
Two-electron atoms possess unique properties which makes them the ideal platform for quantum simulation of strongly correlated systems. I will present the results of two new experiments based on degenerate Fermi gases of ytterbium (Yb), in which we observe the onset of a flavour-selective localized phase as a consequence of the breaking of the intrinsic SU(N) symmetry of Yb atoms, and the emergence of a universal Hall response in a hybrid 2D atomic ladder made of real and synthetic dimensions. Finally, I will present a new experimental platform currently under construction in Florence consisting in a programmable quantum simulator based on Rydberg strontium atoms.
