Exact results in the theory of magnetic alloys
A. M. Tsvelick,Paul Wiegmann +1 more
TL;DR: In this paper, a detailed account of the Bethe-Ansatz technique for the s-d exchange (Kondo) model with arbitrary impurity spin, s-D model with anisotropic exchange, degenerate exchange model and for the canonical Anderson model is given.
Journal ArticleDOI
Theory of nonabelian goldstone bosons in two dimensions
TL;DR: In this article, an exact theory of an O(4)-σ-model based on its relation to a certain fermionic model is presented, and the S-matrix and the vacuum energy in a constant external field are computed.
Journal ArticleDOI
Goldstone fields in two dimensions with multivalued actions
TL;DR: In this paper, an exact solution for the two-dimensional chiral fields with multivalued action is presented, and the relation of this theory to the CP -asymmetric Thirring model, free fermions, surrent algebras and Heisenberg antiferromagnets is discussed.
Journal ArticleDOI
Quantum Integrable Models and Discrete Classical Hirota Equations
TL;DR: In this article, the functional relation for commuting quantum transfer matrices of quantum integrable models is shown to coincide with classical Hirota's bilinear difference equation, which is equivalent to the completely discretized classical 2D Toda lattice with open boundaries.
Journal ArticleDOI
Superconductivity in strongly correlated electronic systems and confinement versus deconfinement phenomenon.
TL;DR: The supersymmetrical gauge theory of strongly correlated electronic systems, based on a geometrical approach to the quantization of the Hubbard model, is presented and it is shown that topological magnetic excitations induce the long-distance interaction between the charged particles.
