Magnetic impurities in the one-dimensional spin-orbital model
, 2000 Using one-dimensional spin-orbital model as a typical example of quantum spin systems with richer symmetries, we study the effect of an isolated impurity on its low energy dynamics in the gapless phase through bosonization and renormalization group ...
