Polarization vortices of thermal emission.
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 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
Polarization vortices, crucial constituents of singular optics, manifest as vortices of polarization states around singularities. Recent progress has linked polarization vortices with bound states in the continuum (BICs) in optical waves. However, this association has not been explored in the realm of thermal emission, which holds the potential for generating arbitrary polarizations in a single thermal emitter. Here, we implement a polarization vortex thermal emitter (PVTE) based on BICs in a photonic crystal slab (PCS), allowing for the generation of various polarization states simultaneously along different directions. Using a custom-designed polarized angle-resolved thermal emission spectrometer (PARTES), we experimentally confirm polarization vortices of thermal emission originating from BICs with different charges and types. The proposed PVTEs present effective strategies for controlling thermal emission and show promising applications in infrared optical technology.
