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

Electromagnetic wave dynamics at the temporal interface (TI), defined as the abrupt change of material properties in time, is fundamentally different from the counterpart at the spatial interface. The cornerstone for understanding the temporal scattering process for waves links to the momentum conservation for the state projections on the energy bands at the TI. Here, we experimentally construct various TIs in synthetic frequency dimension and study temporal scattering processes over the whole band. Different temporal operation scenarios are studied, including band shifting, band unfolding/folding, and also band variation in a two-dimensional case. We develop the spectral tomography method to retrieve wave function distributions after wave scatterings at different TIs and then demonstrate the momentum conservation over the whole band. Our work provides a flexible experimental platform for realizing TIs in the optical frequency range and studying the fundamental temporal scattering processes for photons.
