Researchers Solve Magic Angle Mystery

Exactly a year ago, researchers at MIT reported on observing superconductivity in twisted bilayer graphene – a new experimental platform engineered on two misaligned graphene layers – at "magic angles" near 1.1°. The origin of these angles was a mystery, however. A team at Harvard University has now shown that they appear to be fundamentally connected to quantum Hall wave functions.

Recent experiments have revealed remarkable new features of the optimal doping state of cuprate superconductors, namely, a peak in the specific heat for the hole-doped case and a state with Fermi pockets but only fluctuating antiferromagnetic order for the electron-doped case.
