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…

Integrability of quantum chains: theory and applications to the spin-1/2 chain
Andreas Klümper
In this contribution we review the theory of integrability of quantum systems in one spatial dimension. We introduce the basic concepts such as the Yang-Baxter equation, commuting…
