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…

Pnictides as frustrated quantum antiferromagnet close to a quantum phase transition
Goetz S. Uhrig, Michael Holt, Jaan Oitmaa +2
We present a detailed description of the dynamics of the magnetic modes in the recently discovered superconducting pnictides using reliable self-consistent spin-wave theory and ser…
