Classical Heisenberg spins on a hexagonal lattice with Kitaev couplings Open
We analyze the low temperature properties of a system of classical Heisenberg spins on a hexagonal lattice with Kitaev couplings. For a lattice of 2N sites with periodic boundary conditions, the ground states form an (N+1) dimensional mani…

Exact Entropy of Dimer Coverings for a Class of Lattices in Three or More Dimensions Open
We construct a class of lattices in three and higher dimensions for which the number of dimer coverings can be determined exactly using elementary arguments. These lattices are a generalization of the two-dimensional kagome lattice, and th…
