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…

Thermodynamics of Spin S = 1/2 Antiferromagnetic Uniform and Alternating-Exchange Heisenberg Chains
D. C. Johnston, R. K. Kremer, M. Troyer +5
The magnetic susceptibility chi and specific heat C versus temperature T of the spin-1/2 antiferromagnetic alternating-exchange (J1 and J2) Heisenberg chain are studied for the ent…

Thermodynamics of the Spin-1/2 Antiferromagnetic Uniform Heisenberg Chain
A. Klümper, D. C. Johnston
We present a new application of the traditional thermodynamic Bethe ansatz to the spin-1/2 antiferromagnetic uniform Heisenberg chain and derive exact nonlinear integral equations…
