Thermal and quantum fluctuations in extended Kitaev-Yao-Lee spin-orbital model
This study investigates how thermal and quantum fluctuations cause disorder in an extended Kitaev-Yao-Lee spin-orbital model. Using classical simulations and generalized spin wave theory, researchers found that a disordered nematic phase emerges due to these fluctuations. The inclusion of higher-order interaction terms, especially cubic ones, is crucial for stabilizing this phase.
