Orientation dependence of surface critical phenomena in antiferromagnets: exact results in two dimensions
For an Ising antiferromagnet, we analyze exact expressions for the one- and two-point correlation functions for spins on the edge of a square lattice with a magnetic field applied to the surface sites. Two different edge orientations, with respect to the crystal axes, are treated. At bulk criticalit...
