SU(4) Heisenberg model on the honeycomb lattice with exchange-frustrated perturbations: implications for twistronics and Mott insulators
W. M. H. Natori, R. Nutakki, R. G. Pereira +1
The SU(4)-symmetric spin-orbital model on the honeycomb lattice was recently studied in connection to correlated insulators such as the Mott insulator BaCuSbO$_…

Orbital Magnetic Field Effects in Mott Insulators with Strong Spin-Orbit Coupling
Willian M. H. Natori, Roderich Moessner, Johannes Knolle
We study the effect of a magnetic field on the low energy description of Mott insulators with strong spin-orbit (SO) coupling. In contrast to the standard case of the Hubbard model…
