Thermally activated Peierls dimerization in ferromagnetic spin chains
J. Sirker, A. Herzog, A. M. Oles +1
We demonstrate that a Peierls dimerization can occur in ferromagnetic spin chains activated by thermal fluctuations. The dimer order parameter and entanglement measures are studied…

Thermodynamics of impurities in the anisotropic Heisenberg spin-1/2 chain
J. Sirker, S. Fujimoto, N. Laflorencie +2
The thermodynamics of finite open antiferromagnetic XXZ chains is studied using field theory, Bethe Ansatz and quantum Monte Carlo methods. For the susceptibility a parameter-free…
