  • Shift currents can be traced to a local geometric property defined by the difference in Berry connection between bands participating in the optical transition.

    “Shift currents, resulting from the real space coherent shift of electron density following photoexcitation42, can be traced to a local geometric property defined by the difference in Berry connection between bands participating in the optical transition86,87.”

    From Ultrafast terahertz emission from emerging symmetry-broken materials (2023) · cites this paper as [86]

    The Results (Floquet two-band model; page not provided) identify the local geometric quantity as the shift vector for the two bands involved in the optical transition. But the shift vector includes both the difference in their Berry connections and the momentum derivative of the transition-matrix-element phase; the Berry-connection difference alone does not define it. (LLM, conf=0.87)

  • The second harmonic generation signal can be related to the shift vector R, a gauge-invariant length formed from the momentum derivative of the phase of the velocity matrix element and the difference in the Berry connection.

    “For instance, it can be shown that the second harmonic generation (SHG) signal can be related to the shift vector R , which is a gauge-invariant length formed from the momentum derivative of the phase of the velocity matrix element and the difference in the Berry connection (Morimoto and Nagaosa, 2016).”

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.
