A one-dimensional liquid of fermions with tunable spin — •Massimo Inguscio — LENS & Dipartimento di Fisica e Astronomia, Università di Firenze, Firenze, Italy — INRIM Istituto Nazionale di Ricerca Metrologica, Torino, Italy --- Laureate of the Herbert-Walther-Prize

Ultracold atoms offer an exceptionally rich experimental platform, allowing the most precise metrological measurements and the investigation of fundamental quantum effects in interacting many-body systems [1]. An example is given by ultracold two-electron atoms, which are used to build the most accurate and precise atomic clocks to date. The rich internal structure of these atoms also allows for novel advances in quantum simulation, for instance the investigation of large-spin atomic systems with SU(N) interaction symmetry. We will report on the realization of one-dimensional liquids of fermionic 173Yb with tunable spin, evidencing for the first time intriguing effects arising from the interplay between strong interactions and quantum statistics [2].
