Photovoltaic Hall effect in graphene

Open access
Oka, Takashi, Aoki, Hideo·2009·Physical Review B

Abstract

Response of electronic systems in intense lights (ac electric fields) to dc source-drain fields is formulated with the Floquet method. We have then applied the formalism to graphene, for which we show that a nonlinear effect of a circularly polarized light can open a gap in the Dirac cone, which is predicted to lead to a photoinduced dc Hall current. This is numerically confirmed for a graphene ribbon attached to electrodes with the Keldysh Green's function.

  • In the light-induced anomalous Hall system, the helicity of the optical field breaks symmetry and opens an intensity-dependent topological Floquet band gap, leading to a Chern insulating state with protected edge transport.

    “In this system, the helicity of the optical field breaks symmetry and opens an intensity-dependent topological Floquet band gap249, leading to a Chern insulating state with protected edge transport.”

    From Ultrafast terahertz emission from emerging symmetry-broken materials (2023) · cites this paper as [249]

    The paper reports that circularly polarized light opens a Floquet quasi-energy gap that grows with field strength (p. 2), and that reversing the polarization reverses the photo-induced Hall current (p. 3). It does not establish that the gap produces a Chern insulating state or protected edge transport; its reported Hall current requires a DC bias. (LLM, conf=0.88)

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.
