Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh-Q Cavities and Waveguides.
Article in Advanced materials (Deerfield Beach, Fla.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Compact, robust, and ultralow-loss on-chip photonic devices are essential for densely integrated photonic chips. Conventional designs struggle to achieve these properties due to their inherent trade-offs among compactness, robustness, and low loss. Topological valley photonic crystals (VPCs) offer a promising solution, as their valley-vortex-protected edge states are capable of robustly guiding light through sharp bends and structural perturbations with negligible loss. Notably, exhaustive control over all loss channels is crucial for minimizing undesired losses. However, the intrinsic loss mechanisms in valley edge states remain largely unexplored, severely limiting their full potential. Here, we unveil that radiation is the dominant loss mechanism in valley edge states and propose a new methodology of interface topology driven bandgap and wavevector engineering to thoroughly suppress their radiation losses in chip-scale waveguides and cavities. The methodology minimizes the radiation losses of topological cavities by ≈10
