Domain walls in a doped antiferromagnet
Open accessAbstract
The effects of a small amount of holes on the antiferromagnetic state of the two-dimensional Hubbard model are investigated analytically and numerically. It is found that it is energetically favorable for the system to form domain walls of finite width, with the holes localized in bound states at the walls. For a small but finite concentration of holes, a regularly spaced array of domain walls is formed, i.e. one has an insulating incommensurate antiferromagnet, with a linearly polarized magnetisation pattern and a modulation wavevector proportional to the hole concentration. With increasing electron-electron repulsion, the preferred orientation of the walls changes from parallel to a lattice direction to diagonal. Possible fluctuation effects in the incommensurate phase and relations with recent experiments on La2-xSrxCuO 4 are 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.
