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 ability to coherently manipulate phonons through light permits cooling and heating microscale quantum systems for various critical fields in metrology, information processing, and sensing. However, these physical systems often are hard to isolate and open for exchanging energy externally, making themselves non-Hermitian. Here, we experimentally observe a super-cooling/heating state in a non-Hermitian phononic dimer, where the two independent phonon modes of distinct cooling/heating rates become synchronous in cooling/heating. Such super cooling/heating is manifested in a Parity-Time symmetric state controlled by two counterpropagating optical pumps. These results reveal the non-Hermitian nature of the phonon dimer and illustrate a coherent technique for synchronous cooling/heating non-Hermitian systems, paving the way for practical applications in quantum sensing and metrology.
