Thin-film lithium niobate terahertz differential field detectors with a bandwidth reaching 3 terahertz.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Broadband and sensitive detection of terahertz (THz) radiation is critical for advances in fields like telecommunications, spectroscopy, and quantum physics. We present a compact and high-performance THz field detector based on resonant THz antennas printed along near-infrared waveguides on thin-film lithium-niobate. These antennas were shown to have their peak response between 250 GHz to 1 THz, depending on their geometry, while the non-resonant nature of the interaction enables THz detection to be achieved up to 3 THz. We show that combining two such antennas in an integrated Mach Zehnder interferometer allows for a measurement of the discrete time derivative of the THz waveform, while using a single antenna measures the instantaneous derivative of the field. Using this approach, we have achieved a noise equivalent intra-cavity field as low as 1.9 Vm
