Fractionalized fermionic multicriticality in anisotropic Kitaev spin-orbital liquids

Year: 2025

Type: article

Abstract: Fractionalized quasiparticles in frustrated many-body systems can give rise to emergent quantum phenomena absent in conventional settings. Here, the authors investigate a frustrated quantum spin-orbital model with XXZ spin anisotropy and uncover three distinct fractionalized liquid phases, each defined by unique symmetry properties. Most notably, they identify a multicritical point in the phase diagram where spin rotational symmetry emerges, despite its explicit absence in the underlying microscopic model.
