Topological magnonics in the two-dimensional van der Waals magnet CrI3

Esteban Aguilera, Rodrigo Jaeschke-Ubiergo, Nicolas Vidal-Silva +2

In this article, we calculate the magnon spectrum of Kitaev-Heisenberg magnets. This model has been recently proposed as a spin Hamiltonian to model ${\text{CrI}}_3$ and other two-di…
