Quantum versus classical behavior in the boundary susceptibility of the ferromagnetic Heisenberg chain
J. Sirker, M. Bortz
We calculate the temperature dependence of the boundary susceptibility for the quantum ferromagnetic Heisenberg chain by a modified spin-wave theory (MSWT). We find that $χ_B…

Exact results for the 1D interacting mixed Bose-Fermi gas
M. T. Batchelor, M. Bortz, X. W. Guan +1
The exact solution of the 1D interacting mixed Bose-Fermi gas is used to calculate ground-state properties both for finite systems and in the thermodynamic limit. The quasimomentum…

Boundary susceptibility in the open XXZ-chain
Michael Bortz, Jesko Sirker
In the first part we calculate the boundary susceptibility in the open -chain at zero temperature and arbitrary magnetic field by Bethe ansatz. We present analytical…
