Frustrated magnetic order in hybrid Kitaev spin-orbital models
Ivan Dutta, Aayush Vijayvargia, Anamitra Mukherjee +2
Spin-orbital generalization of Kitaev model provides a robust extension to the original Kitaev model. However, real materials often exhibit competing interactions that break exact…

Exactly solvable spin liquids in Kitaev bilayers and moiré superlattices
Ivan Dutta, Anamitra Mukherjee, Onur Erten +1
Building on the recent advancements on moiré superlattices, we propose an exactly solvable model with Kitaev-type interactions on a bilayer honeycomb lattice for both AA stacking a…

Disorder-induced delocalization and reentrance in a Chern-Hopf insulator
Soumya Bera, Ivan Dutta, Roderich Moessner +1
The Chern-Hopf insulator is an unconventional three-dimensional topological insulator with a bulk gap and gapless boundary states without protection from global discrete symmetries…
