Topological transitions in the Yao-Lee spin-orbital model and effects of site disorder
Vladislav Poliakov, Wen-Han Kao, Natalia B. Perkins
The Yao-Lee model is an example of exactly solvable spin-orbital models that are generalizations of the original Kitaev honeycomb model with extra local orbital degrees of freedom.…

Dynamics of vacancy-induced modes in the non-Abelian Kitaev spin liquid
Wen-Han Kao, Gábor B. Halász, Natalia B. Perkins
We study the dynamical response of vacancy-induced quasiparticle excitations in the site-diluted Kitaev spin liquid with a magnetic field. Due to the flux-binding effect and the em…
