Integrable Anderson-type impurity in the supersymmetric $t$–$J$ model
H. Frahm, G. Palacios Leibniz University of Hannover
Abstract:
We solve an integrable $gl(2\mid 1)$-symmetric model of correlated electrons with
an Anderson-type impurity constructed in the framework of the algebraic Bethe
ansatz. Depending on the parameters characterizing the impurity and its
coupling to the chain, we observe the formation of bound states in
the spectrum of the system. We study the effect of these bound states on
the contribution of the impurity to the low-temperature characteristics of
the system, in particular, its magnetization and susceptibility.
Keywords:
Kondo effect, quantum impurity, Bethe ansatz, boundary condition.
