Lattice path integral approach to the one-dimensional Kondo model
Michael Bortz, Andreas Kluemper
An integrable Anderson-like impurity model in a correlated host is derived from a gl(21)-symmetric transfer matrix by means of the Quantum-Inverse-Scattering-Method (QISM). Usin…

Correlation length of the 1D Hubbard Model at half-filling : equal-time one-particle Green's function
Y. Umeno, M. Shiroishi, A. Kluemper
The asymptotics of the equal-time one-particle Green's function for the half-filled one-dimensional Hubbard model is studied at finite temperature. We calculate its correlation len…
