Anomalous excitation spectra of frustrated quantum antiferromagnets.

Anomalous excitation spectra of frustrated quantum antiferromagnets.

We use series expansions to study the excitation spectra of spin-1/2 antiferromagnets on anisotropic triangular lattices. For the isotropic triangular lattice model (TLM), the high-energy spectra show several anomalous features that differ strongly from linear spin-wave theory (LSWT). Even in the Né...
