Crossover from Anderson- to Kondo-like behavior: Universality induced by spin-charge separation
Michael Bortz, Andreas Klümper, Christian Scheeren
The thermodynamics of a lattice regularized asymmetric Anderson impurity in a correlated host is obtained by an exact solution. The crossover from the Anderson- to the Kondo-regime…

On the finite temperature Drude weight of the anisotropic Heisenberg chain
J. Benz, T. Fukui, A. Klümper +1
We present a study of the Drude weight of the spin-1/2 chain in the gapless regime. The thermodynamic Bethe ansatz (TBA) is applied in two different ways. In the first…

The 1/2-XXZ spin-chain at finite magnetic field: Crossover phenomena driven by temperature
A. Klümper, J. R. Reyes Martínez, C. Scheeren +1
We investigate the asymptotic behaviour of spin-spin correlation functions for the integrable Heisenberg chain. To this end we use the Quantum Transfer Matrix (QTM) technique devel…
