Anisotropy-driven topological quantum phase transition in magnetic impurities
A few years ago, a topological quantum phase transition (TQPT) has been found in Anderson and Kondo 2-channel spin-1 impurity models that include a hard-axis anisotropy term $DS_z^2$ with D > 0. The most remarkable manifestation of the TQPT is a jump in the spectral density of localized electron...
