Abstract

Optical excitation of apical oxygen vibrations in $\mathrm{YB}{\mathrm{a}}_{2}\mathrm{C}{\mathrm{u}}_{3}{\mathrm{O}}_{6+\ensuremath{\delta}}$ has been shown to enhance its $c$ axis superconducting-phase rigidity, as evidenced by a transient blueshift of the equilibrium interbilayer Josephson plasma resonance. Surprisingly, a transient $c$ axis plasma mode could also be induced above ${T}_{c}$ by the same apical oxygen excitation, suggesting light activated superfluid tunneling throughout the pseudogap phase of $\mathrm{YB}{\mathrm{a}}_{2}\mathrm{C}{\mathrm{u}}_{3}{\mathrm{O}}_{6+\ensuremath{\delta}}$. However, despite the similarities between the transient plasma mode above ${T}_{c}$ and the equilibrium Josephson plasmon, alternative explanations involving high-mobility quasiparticle transport should be considered. Here, we report an extensive study of the relaxation of the light induced plasmon into the equilibrium incoherent phase. These new experiments allow for a critical assessment of the nature of this mode. We determine that the transient plasma relaxes through a collapse of its coherence length rather than its carrier (or superfluid) density. These observations are not easily reconciled with quasiparticle interlayer transport and rather support transient superfluid tunneling as the origin of the light induced interlayer coupling in $\mathrm{YB}{\mathrm{a}}_{2}\mathrm{C}{\mathrm{u}}_{3}{\mathrm{O}}_{6+\ensuremath{\delta}}$.

  • Buzzi et al. [11] considered the role of heating in their measurements and found that it could not explain their observations.

    “Buzzi et al. [11] considered the role of heating in their measurements and found that it could not explain their observations.”

    From Optical Saturation Produces Spurious Evidence for Photoinduced Superconductivity in K 3 C 60 (2023) · cites this paper as [11]

    In “Light-induced plasma mode” (page unavailable), the paper considers heating, but says it is consistent with the observed response in optimally doped YBCO 7. The cited paper is by Hunt et al., not Buzzi et al., and the passage does not establish the blanket claim that heating could not explain their observations. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • Niwa et al. [8] showed that Pth provides a better description of their measurements than Pexp, and found that the image spectrum σs(ω,T;Pth↦Pexp) displays artifacts that are reminiscent of the results reported for K3C60 by Buzzi et al. [11], including σ1 < 0 and Radj > 1.

    “In an experiment that examined how photoexcitation destroys superconductivity in La 2 -x Sr x CuO4, Niwa et al. [8] showed that P th provides a better description of their measurements than P exp , and found that the image spectrum σ s ( ω, T ; P th ↦→P exp ) displays artifacts that are reminiscent of the results reported for K3C60 by Buzzi et al. [11], including σ 1 &lt; 0 and R adj &gt; 1.”

  • The observations of Buzzi et al. [11] are consistent with a saturable photoenhancement of the mobility.

    The Abstract and IV. Summary discuss light-induced interlayer coupling in YBa₂Cu₃O₆₊δ and favor transient superfluid tunneling over a high-mobility quasiparticle explanation. Searches for Buzzi, saturable photoenhancement, and mobility saturation found no passage assessing Buzzi et al.’s observations or the proposed saturable mobility enhancement. (LLM, conf=0.77)

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.
