Correlations in the Ising antiferromagnet on the anisotropic kagome lattice
Walter Apel, Hans-Ulrich Everts
We study the correlation function of middle spins, i. e. of spins on intermediate sites between two adjacent parallel lattice axes, of the spatially anisotropic Ising antiferromagn…
Finite-temperature ordering in a two-dimensional highly frustrated spin model
A. Honecker, D. C. Cabra, H. -U. Everts +2
We investigate the classical counterpart of an effective Hamiltonian for a strongly trimerized kagome lattice. Although the Hamiltonian only has a discrete symmetry, the classical…
Diffusion in a strongly correlated anisotropic overlayer
Igor F. Lyuksyutov, H. -U. Everts, H. Pfnuer
We study the collective diffusion in chain structures on anisotropic substrates like (112) bcc and (110) fcc surfaces with deep troughs in the substrate potential corrugation. Thes…
First excitations of the spin 1/2 Heisenberg antiferromagnet on the kagomé lattice
Ch. Waldtmann, H. -U. Everts, B. Bernu +4
We study the exact low energy spectra of the spin 1/2 Heisenberg antiferromagnet on small samples of the kagomé lattice of up to N=36 sites. In agreement with the conclusions of pr…
