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

Strong light-matter coupling occurs when the rate of energy exchange between the electromagnetic mode and the molecular ensemble exceeds the competitive dissipation process. Coupled photon molecules with near-field light-matter interactions may produce new hybridized states when they reach the strong coupling region. Tunable Terahertz (THz) meta materials can be used to design sensors, optical modulators, etc., to improve imaging sensitivity and resolution. In this work, we use the scattering-type scanning near-field microscopy (s-SNOM) to demonstrate an angle-controlled coupling strength in a tunable photon molecules system. The system consists of a base waveguide layer and a single ribbon structure. By changing the in-plane angle between ribbon and incidence, the coupling strength between ribbon resonance and waveguide mode ranges from 0.03 to 0.08 THz, leading to the system's transformation from weak to strong coupling. This work offers a new platform for actively controlling strong light-matter interaction and further applications in strong coupling.
