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

In the terahertz (THz) range, due to the lack of effective THz light sources, chaos generation in THz semiconductor lasers, e.g., quantum cascade lasers (QCLs), is particularly challenging. Here, we experimentally demonstrate a THz chaos source based on a sole multimode THz QCL without any external perturbations. Such a dynamical regime is characterized by the largest Lyapunov exponent of the measured radio frequency signal of the laser. The experimental results are confirmed by our simulations based on effective semiconductor Maxwell-Bloch Equations. Furthermore, a reduced model based on two coupled complex Ginzburg-Landau equations is derived to systematically investigate the effects of the linewidth enhancement factor and group velocity dispersion on the chaotic regime. It is found that the chaos generation in the THz QCL is ascribed to the defect-mediated turbulence. Our findings pave the way for the generation of controllable and integrated THz chaos sources, as well as potential applications.
