Flat-band ferromagnetism and spin waves in the Haldane-Hubbard model

LSG Leite, RL Doretto - Physical Review B, 2021 - APS
We study the flat-band ferromagnetic phase of the Haldane-Hubbard model on a
honeycomb lattice within a bosonization scheme for flat-band Chern insulators, focusing on …

Flat-band ferromagnetism in a correlated topological insulator on a honeycomb lattice

LSG Leite, RL Doretto - Physical Review B, 2022 - APS
We study the flat-band ferromagnetic phase of a spinfull and time-reversal symmetric
Haldane-Hubbard model on a honeycomb lattice within a bosonization formalism for flat …
