Coherent acoustic frequency comb via floquet engineering of optical tweezer phonon lasers.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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 engineering, featuring time-periodic control of various systems, has enabled observations of many exotic phenomena such as time crystals, breaking of reciprocity symmetry, and exceptional topology. Theoretically, a periodic drive can make the system inherit the time period and generate new harmonics or distort the band structure at the fundamental frequency. Here, by combining such a technique with levitated optomechanics, we present an instructive example of a coherent acoustic frequency comb with microsphere phonon lasers. This work shows that our technique offers the capability of flexibly controlling both the teeth number and the teeth spacing of the resulting coherent acoustic frequency comb. In particular, we confirm that all Floquet-driven comb teeth can reach the truly coherent regime, i.e., satisfying all the characteristic features of phonon lasers. Our work provides a platform to drive the nonlinear phonon laser to a coherent acoustic frequency comb with truly coherent comb teeth.
