Triangular Ising antiferromagnet in a staggered field
Triangular Ising antiferromagnet in a staggered field
We study the equilibrium properties of the nearest-neighbor Ising antiferromagnet on a triangular lattice in the presence of a staggered field conjugate to one of the degenerate ground states. Using a mapping of the ground states of the model without the staggered field to dimer coverings on the dual lattice, …
