Ferromagnetism in tilted fermionic Mott insulators
Kazuaki Takasan, Masaki Tezuka
We investigate the magnetism in tilted fermionic Mott insulators. With a small tilt, the fermions are still localized and form a Mott-insulating state, where the localized spins in…

A model of randomly-coupled Pauli spins
Masanori Hanada, Antal Jevicki, Xianlong Liu +2
We construct a model of Pauli spin operators with all-to-all 4-local interactions by replacing Majorana fermions in the SYK model with spin operators. Equivalently, we replace ferm…
