Spin-lattice coupling effects in the Holstein double-exchange model
Alexander Weisse, Holger Fehske, Dieter Ihle
Based on the Holstein double-exchange model and a highly efficient single cluster Monte Carlo approach we study the interplay of double-exchange and polaron effects in doped coloss…

Dynamic spin susceptibility in the t-J model
G. Jackeli, N. M. Plakida
Dynamic spin susceptibility is calculated for the t-J model in the paramagnetic phase by applying the memory function method in terms of the Hubbard operators. A self-consistent sy…

Magnetic Order-Disorder Transition in the Two-Dimensional Spatially Anisotropic Heisenberg Model at Zero Temperature
D. Ihle, C. Schindelin, A. Weisse +1
The ground-state properties of the spin-1/2 antiferromagnetic Heisenberg model with spatially anisotropic couplings on a square lattice are investigated by a spin-rotation-invarian…
