Emergent Spinon Dispersion and Symmetry Breaking in Two-Channel Kondo Lattices

Two-channel Kondo lattice serves as a model for a growing family of heavy-fermion compounds. We employ a dynamical large-N technique and go beyond the independent bath approximation to study this model both numerically and analytically using renormalization group ideas. We show that the Kondo effect induces dynamic magnetic correlations that lead to an emergent spinon dispersion. Furthermore, we develop a quantitative framework that interpolates between infinite dimension where the channelsymmetry broken results of mean-field theory are confirmed, and one-dimension where the channel symmetry is restored and a critical fractionalized mode is found.

Automated summary

Researchers have studied the two-channel Kondo lattice model using a dynamical large-N technique and renormalization group ideas, going beyond the independent bath approximation. They found that the Kondo effect results in dynamic magnetic correlations and the emergence of spinon dispersion. Additionally, they developed a quantitative framework that interpolates between different dimensions.
