Spin-orbit and impurity scattering in an integrable electron model: Exact results for dynamic correlations
A. A. Zvyagin, H. Johannesson
We introduce an integrable model of spin-polarized interacting electrons subject to a spin-conserving spin-orbit interaction. Using Bethe Ansatz and conformal field theory we calcu…
Superconductivity and Antiferromagnetism: Hybridization Impurities in a Two-Band Spin-Gapped Electron System
A. A. Zvyagin, H. Johannesson
We present the exact solution of a one-dimensional model of a spin-gapped correlated electron system with hybridization impurities exhibiting both magnetic and mixed-valence proper…
Hidden Kondo Effect in a Correlated Electron Chain
A. A. Zvyagin, H. Johannesson
We develop a general Bethe Ansatz formalism for diagonalizing an integrable model of a magnetic impurity of arbitrary spin coupled ferro- or antiferromagnetically to a chain of int…
Multichannel Kondo Effect in an Interacting Electron System: Exact Results for the Low-Temperature Thermodynamics
M. Granath, H. Johannesson
We study the low-temperature thermodynamics of a spin-S magnetic impurity coupled to m degenerate bands of interacting electrons in one dimension. By exploiting boundary conformal…
