MIT reports nodal, unconventional superconductivity in magic‑angle graphene — Nov. 7, 2025

Published: Friday, November 7, 2025Topic: Magic‑angle graphene, superconductivity, twistronics, condensed‑matter physics What happened MIT physicists have presented the clearest evidence so far that magic‑angle twisted trilayer graphene (MATTG) hosts unconventional, nodal superconductivity. The results, published in Science on November 6, show a distinctive V‑shaped superconducting gap—a hallmark of non‑BCS (non‑conventional) pairing—captured with a custom platform that combines tunneling spectroscopy and transport on an all–van der Waals stack. MIT News+2EurekAlert!+2 On the same news cycle (Nov. 7), international outlets amplified the finding, and Nature Physics ran a companion News & Views analysis (published Nov. 6) placing trilayer graphene’s superconductivity into a

Quantum Tunneling Goes Big: The Tiny Circuit Experiment That Won the 2025 Nobel Prize in Physics

Quantum Tunneling, Explained At the heart of this Nobel-winning discovery is a phenomenon straight out of quantum theory: quantum tunneling. In classical physics, if you throw a ball at a solid wall, it will always bounce back – it doesn’t have enough energy to break through. By analogy, an electron trapped in a low-energy state cannot classically overcome a higher-energy barrier. But quantum mechanics allows for a spooky exception: the particle can sometimes “tunnel” through the barrier and appear on the other side, as if by ghostly permission of probability nobelprize.org nobelprize.org. This is a well-known microscopic effect – it
