The Fate of the Two-Magnon Bound State in the Heisenberg Antiferromagnet
C. J. Hamer
The energy spectrum of the two-magnon bound states in the Heisenberg-Ising antiferromagnet on the square lattice are calculated using series expansion methods. The results confirm…

Critical Behaviour of Structure Factors at a Quantum Phase Transition
C. J. Hamer
We review the theoretical behaviour of the total and one-particle structure factors at a quantum phase transition for temperature T=0. The predictions are compared with exact or nu…
