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.
