Abstract

The photocurrent in an optically active metal is known to contain a component that switches sign with the helicity of the incident radiation. At low frequencies, this current depends on the orbital Berry phase of the Bloch electrons via the "anomalous velocity" of Karplus and Luttinger. We consider quantum wells in which the parent material, such as GaAs, is not optically active and the relevant Berry phase only arises as a result of quantum confinement. Using an envelope approximation that is supported by numerical tight-binding results, it is shown that the Berry-phase contribution is determined for realistic wells by a cubic Berry phase intrinsic to the bulk material, the well width, and the well direction. These results for the Berry-phase effect suggest that it may already have been observed in quantum well experiments.

  • Nonlinear optical effects such as high harmonic generation, photovoltaic effects, shift currents, and nonlinear Kerr rotations are related to the Berry connection and Berry curvature.

    “Generally these effects such as high harmonic generation, photovoltaic effects, shift (dc) currents, and nonlinear Kerr rotations, are related to the Berry connection and Berry curvature (Hosur, 2011; Moore and Orenstein, 2010).”

    The paper states that Berry-phase contributions produce circular and linear photogalvanic photocurrents (p. 2), supporting the claim for those nonlinear dc optical effects. It does not connect high harmonic generation, shift currents, or nonlinear Kerr rotations to the Berry connection or curvature. It also distinguishes its Berry-phase photogalvanic terms from the more typical photovoltaic term in Eq. 8 (p. 2). (LLM, conf=0.88)

  • The CPGE can be shown to be sensitive to the anomalous velocity derived by Karplus and Luttinger, later interpreted as a Berry-phase effect.

    “It can be shown (Moore and Orenstein, 2010) to be sensitive to the anomalous velocity derived by Karplus and Luttinger (Karplus and Luttinger, 1954) that was later interpreted as a Berry-phase effect (Jungwirth et al. , 2002; Sundaram and Niu, 1999).”

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.
