Deciphering competing interactions of Kitaev-Heisenberg-$\hat{I}“$ system in clusters: part II -- dynamics of Majorana fermions

Sheikh Moonsun Pervez, Saptarshi Mandal

We perform a systematic and exact study of Majorana fermion dynamics in the Kitaev-Heisenberg-$\hat{I}“$ model in a few finite-size clusters increasing in size up to twelve sites. We emp…
