Thermodynamics of antiferromagnetic alternating spin chains
G. A. P. Ribeiro, A. Klümper
We consider integrable quantum spin chains with alternating spins (S_1,S_2). We derive a finite set of non-linear integral equations for the thermodynamics of these models by use o…

From multiple integrals to Fredholm determinants
Alexander Seel, Frank Göhmann, Andreas Klümper
We consider a multiple integral representation for the finite temperature density-density correlation functions of the one-dimensional Bose gas with delta function interaction in t…

Quantum phase transitions and thermodynamics of quantum antiferromagnets with competing interactions
Christian Trippe, Andreas Klümper
We study the isotropic Heisenberg chain with nearest and next-nearest neighbour interactions. The ground state phase diagram is constructed in dependence on the additonal interacti…
