Effective Hamiltonians for state selection in Heisenberg antiferromagnets
Brond E. Larson, Christopher L. Henley
In frustrated antiferromagnets with isotropic exchange interactions, there is typically a manifold of degenerate classical ground states. This degeneracy is broken by the (free) en…
Matching rules from Al-Co potentials in an almost realistic model
Sejoon Lim, M. Mihalkovic, C. L. Henley
We consider a model decagonal quasicrystal of composition AlCo -- closely related to actual structures, and using realistic pair potentials -- on a quasilattice o…
Penrose Matching Rules from Realistic Potentials in a Model System
Sejoon Lim, M. Mihalkovic, C. L. Henley
We exhibit a toy model of a binary decagonal Al-Co quasicrystal -- closely related to actual structures -- in which realistic pair potentials yield a ground state which appears to…
Depleted pyrochlore antiferromagnets
Christopher L. Henley
I consider the class of "depleted pyrochlore" lattices of corner-sharing triangles, made by removing spins from a pyrochlore lattice such that every tetrahedron loses exactly one.…
