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

Realizing programmable topological states in quantum anomalous Hall (QAH) insulators requires tuning their topological invariant, the Chern number C. Here we report a QAH platform based on twisted rhombohedral graphene, in which C becomes a programmable and electrically tunable degree of freedom. In twisted monolayer-multilayer (1 + N) rhombohedral graphene, we find QAH states with C = N, where the layer number N = 3, 4, 5 directly sets the Chern number. We further demonstrate in situ electrical control. In a twisted monolayer-trilayer device, the sign of C is switched by electrostatic doping or displacement field. In addition, in twisted Bernal bilayer-rhombohedral tetralayer graphene, we drive a displacement-field-induced topological phase transition between two distinct QAH states with C = 3 and C = 4. Our work establishes a layer-engineered and electrically tunable platform that could lead to the on-demand engineering of correlated topological states.
