Magnon spectra of cuprates beyond spin wave theory
Open accessPublished version of a preprint
Abstract
The usual starting point for understanding magnons in cuprate antiferromagnets such as La 2 CuO 4 is a spin model incorporating cyclic exchange, which descends from a one-band Hubbard model, and has parameters taken from fits based on non-interacting spin wave theory. Here we explore whether this provides a reliable description of experiment, using matrix product states (MPS) to calculate magnon spectra beyond spin wave theory. We find that analysis based on low orders of spin wave theory leads to systematic overestimates of exchange parameters, with corresponding errors in estimates of Hubbard t / U . Once these are corrected, the “standard” model provides a good account of magnon dispersion and lineshape in La 2 CuO 4 , but fails to fully capture the continuum observed at high energies. The extension of this analysis to CaCuO 2 and Sr 2 IrO 4 is also discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
