Article summary:
1. The article discusses the observation of strongly coupled superconductivity in a magic-angle twisted trilayer graphene (MATTG) system.
2. The MATTG system has a larger magic angle than the previously studied magic-angle twisted bilayer graphene (MATBG), and its flat bands can be hybridized with Dirac bands by applying an electric displacement field.
3. Robust superconductivity was observed in three MATTG devices, with a twist angle close to θMATTG, and the coexistence of Dirac bands and flat bands was confirmed by transport data under a perpendicular magnetic field.
Article analysis:
The article is generally reliable and trustworthy, as it provides evidence for its claims through calculations, experiments, and observations. The authors provide detailed descriptions of their methods and results, which are supported by references to other studies in the field. Furthermore, they discuss potential risks associated with their findings, such as possible effects on device performance due to strong coupling between electrons in the flat bands.
However, there are some points that could be improved upon in terms of trustworthiness and reliability. For example, while the authors discuss potential risks associated with their findings, they do not explore any counterarguments or alternative perspectives on these risks. Additionally, while they provide evidence for their claims through calculations and experiments, they do not present any evidence from other sources that could corroborate their findings or provide additional insights into them. Finally, there is no discussion of possible biases or partiality in the article; while this may not necessarily affect its trustworthiness or reliability directly, it would be beneficial to consider potential sources of bias when interpreting the results presented here.
