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…
Kondo Resonance in a Mesoscopic Ring Coupled to a Quantum Dot: Exact Results for the Aharonov-Bohm/Casher Effects
H. -P. Eckle, H. Johannesson, C. A. Stafford
We study the persistent currents induced by both the Aharonov-Bohm and Aharonov-Casher effects in a one-dimensional mesoscopic ring coupled to a side-branch quantum dot at Kondo re…
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…
Two-Species Reaction-Diffusion System with Equal Diffusion Constants: Anomalous Density Decay at Large Times
Zoran Konkoli, Henrik Johannesson
We study a two-species reaction-diffusion model where A+A->0, A+B->0 and B+B->0, with annihilation rates lambda0, delta0 > lambda0 and lambda0, respectively. The initial particle c…
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…
Kondo Effect in a Luttinger Liquid: Exact Results from Conformal Field Theory
Per Frojdh, Henrik Johannesson
We report on exact results for the low-temperature thermodynamics of a spin- magnetic impurity coupled to a one-dimensional interacting electron system. By using bound…
