Spin density wave and soft phonon mode from nesting Fermi surfaces
Open accessAbstract
The problems of spin density wave and of soft phonon mode leading to periodic lattice distortion as a consequence of nesting Fermi surfaces have been investigated. By examining the changes in the energy functional of the electron-lattice system as small amplitude spin density wave and periodic lattice distortion develop, the necessary and sufficient criteria for the existence of each kind of instability and for the coexistence of the two kinds have been derived. These results are expressed in terms of the generalized susceptibility function of the electron system, the Coulomb and exchange interactions between the electrons, the electron-phonon coupling and the phonon frequency.

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.
