Phonon dynamics in the Kitaev spin liquid
Mengxing Ye, Rafael M. Fernandes, Natalia B. Perkins
Abstract
The authors show that in the Kitaev spin liquid, while the Majorana fermions evade a strong decay due to the gradient form of the spin-lattice coupling, the study of phonon dynamics is an indirect probe of fractionalization of spin degrees of freedom.
