Flat-band ferromagnetism in the SU() Hubbard and Kondo lattice models
Kensuke Tamura, Hosho Katsura
We develop a general theory of flat-band ferromagnetism in the SU() Fermi-Hubbard model, which describes the behavior of -component fermions with SU() symmetric interactio…
Quantum many-body scars of spinless fermions with density-assisted hopping in higher dimensions
Kensuke Tamura, Hosho Katsura
We introduce a class of spinless fermion models that exhibit quantum many-body scars (QMBS) originating from kinetic constraints in the form of density-assisted hopping. The models…
Ferromagnetism in -dimensional SU() Hubbard models with nearly flat bands
Kensuke Tamura, Hosho Katsura
We present rigorous results for the SU() Fermi-Hubbard models with finite-range hopping in () dimensions. The models are defined on a class of decorated lattices. We…
Ferromagnetism in the SU() Hubbard model with a nearly flat band
Kensuke Tamura, Hosho Katsura
We present rigorous results for the SU() Fermi-Hubbard model on the railroad-trestle lattice. We first study the model with a flat band at the bottom of the single-particle spec…
