The Open XXZ-Chain: Bosonization, the Bethe Ansatz and Logarithmic Corrections

Sirker, Jesko; Bortz, Michael


We calculate the bulk and boundary parts of the free energy for an open spin-1/2 XXZ-chain in the critical regime by bosonization. We identify the cut-off independent contributions and determine their amplitudes by comparing with Bethe ansatz calculations at zero temperature T. For the bulk part of the free energy we find agreement with Lukyanov's result (1998 Nucl. Phys. B 522533). In the boundary part we obtain a cut-off independent term which is linear in T and determines the temperature...[Show more]
