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…

Quantum Phase Diagram and Excitations for the One-Dimensional S=1 Heisenberg Antiferromagnet with Single-Ion Anisotropy
A. Fabricio Albuquerque, Chris J. Hamer, Jaan Oitmaa
We investigate the zero-temperature phase diagram of the one-dimensional S=1 Heisenberg antiferromagnet with single-ion anisotropy. By employing high-order series expansions and qu…
