论文摘要
两通道的近野晶格是不断增长的重型特征化合物家族的模型。我们采用动力学大N技术,并超越独立浴缸的近似值,使用重新归一化组的思想在数值和分析上研究该模型。我们表明,近藤效应诱导了导致新兴旋子分散体的动态磁相关性。此外,我们开发了一个定量框架,该框架在无限的维度之间进行了插值,其中确认了均值对称性的损坏结果,并发现了恢复通道对称性并发现关键分数化模式的一维。
Two-channel Kondo lattice serves as a model for a growing family of heavy-fermion compounds. We employ the 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 channel-symmetry broken results of mean-field theory are confirmed, and one-dimension where the channel symmetry is restored and a critical fractionalized mode is found.
