1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The recent discovery of three-dimensional (3D) quantum Hall effect (QHE) of Fermi arcs in topological semimetals has revolutionized our understanding of Hall physics in 3D systems. However, its most prominent hallmark, the one-sided chiral hinge states of Fermi arcs, has thus far never been experimentally observed in any physical system. Here, we report the first photonic realization of 3D QHE of Fermi arcs and directly observe the one-sided chiral hinge states of Fermi arcs in an inhomogeneous magnetic Weyl photonic crystal under a pseudomagnetic field (PMF) with time-reversal symmetry breaking. We experimentally demonstrate that the PMF quantizes both the bulk and Fermi arc surface states into Landau plateaus, giving rise to chiral Landau levels and robust one-sided chiral hinge states localized at only one edge on the front surface and at the opposite edge on the back surface, both of which are the signatures of 3D QHE of Fermi arcs. Moreover, we show that the one-sided chiral hinge states of Fermi arcs can be switched between the two pairs of diagonal hinges by reversing the PMF. Our work not only provides an ideal platform for exploring 3D quantum Hall physics but also opens new avenues for the design of robust photonic devices.
