Spontaneous polarization of the Kondo problem associated with the higher-spin six-vertex model
Nobuhisa Fukushima, Takeo Kojima
Abstract
We study the multi-channel Kondo model associated with an integrable higher-spin analogue of the anti-ferroelectric six-vertex model, which is constructed by inserting spin ½ to spin 1 lines: We formulate the problem in terms of representation theory of quantum affine algebra [1]. We derive an exact formula for the spontaneous staggered polarization for our model, which corresponds to Baxter's formula [2] for the six-vertex model.
