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

Floquet time crystals, characterized by momentum band gaps (k-gaps), offer powerful mechanisms for exotic wave control. However, selectively harnessing the Floquet band structure and opening multiple k-gaps remains a significant challenge in experiment. In this work, we construct a phononic time crystal by integrating discrete resonant meta-atoms into a one-dimensional acoustic waveguide, effectively creating a time-varying metamaterial. Through dynamic compressibility modulation, we observe amplified transmission and strong emission enhancement for a compact Floquet slab at the k-gap-associated frequency. Based on this versatile platform, we further extend the Floquet band physics by introducing a temporal-supercell concept that creates multiple k-gaps via momentum band folding. By suitably designing the compressibility in each phase of the supercell, we experimentally observe two clear amplified transmission frequency ranges around half and quarter of the original modulation frequency, for a corresponding compact Floquet slab with a band-folding-induced k-gap. This reconfigurable platform enables tailored parametric processes and unlocks pathways to higher-dimensional time crystals and topological temporal phenomena.
