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…

Absence of Hole Confinement in Transition Metal Oxides with Orbital Degeneracy
M. Daghofer, K. Wohlfeld, A. M. Oles +2
We investigate the spectral properties of a hole moving in a two-dimensional Hubbard model for strongly correlated t_2g electrons. Although superexchange interactions are Ising-lik…
