An SU(N) Mott insulator of an atomic Fermi gas realized by large-spin Pomeranchuk cooling
Shintaro Taie, Rekishu Yamazaki, Seiji Sugawa +1
The Hubbard model, containing only the minimum ingredients of nearest neighbor hopping and on-site interaction for correlated electrons, has succeeded in accounting for diverse phe…
Interaction and filling induced quantum phases of dual Mott insulators of bosons and fermions
Seiji Sugawa, Kensuke Inaba, Shintaro Taie +3
Many-body effects are at the very heart of diverse phenomena found in condensed-matter physics. One striking example is the Mott insulator phase where conductivity is suppressed as…
Realization of SU(2)*SU(6) Fermi System
Shintaro Taie, Yosuke Takasu, Seiji Sugawa +4
We report the realization of a novel degenerate Fermi mixture with an SU(2)*SU(6) symmetry in a cold atomic gas. We successfully cool the mixture of the two fermionic isotopes of y…
