WebSep 27, 2024 · Here, we report transport measurements of a magic angle tBLG device that exhibits both correlated insulating and superconducting states. Unexpectedly, the twist angle is measured to be 0.93° ± 0.01°, which is 15% smaller than the already established magic angles (7–9) and is the smallest reported to date that exhibits superconductivity.A … Webvariational Monte Carlo method. At 1/4 doping the system is a chiral spin-density wave state exhibiting the anomalous quantized Hall effect. When the doping deviates from 1/4, the d x 2−y +id xy Cooper pairing becomes the leading instability. Our results suggest that near 1/4 electron or hole doping (away from the neutral point)
