Ultracold Gases of Ytterbium: Ferromagnetism and Mott States in an SU(6) Fermi System

M. A. Cazalilla, A. F. Ho, M. Ueda

It is argued that ultracold quantum degenerate gas of ytterbium ${}^{173}$Yb atoms having nuclear spin $I=5/2$ exhibits an enlarged SU$(6)$ symmetry. Within the Landau Fermi liquid…
