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 $e_g$ Mott insulator Ba${}_3$CuSb${}_2$O$_…
