American physicists have, for the first time, directly witnessed crucial evidence of unconventional superconductivity in magic - angle twisted trilayer graphene (MATTG). This discovery represents a major leap forward in the quest for room - temperature superconductivity.

The researchers carried out experiments under conditions extremely close to absolute zero. They employed a cutting - edge experimental platform that integrates electron tunneling measurements with electrical transport tests. When the material transitioned into the superconducting state, a clearly defined superconducting tunneling gap emerged, showcasing a distinctive V - shaped curve.

In the context of Western scientific understanding, this unique curve is a telltale sign. It implies that the electron pairing mechanism in MATTG is fundamentally different from that of conventional superconductors. Conventional superconductors have a well - established electron pairing pattern, but MATTG's superconductivity is likely driven by strong electron interactions. In the English - speaking scientific community, the concept of electron interactions playing a key role in superconductivity has been a topic of intense research and debate.

The newly developed experimental platform provides a novel avenue for delving into electron pairing mechanisms. The research team has ambitions to leverage this platform to investigate a wider range of two - dimensional twisted structures and materials. This could potentially offer fresh perspectives for designing innovative superconductors and materials suitable for quantum computing, which is a highly sought - after field in modern physics with vast technological implications.
