Research shows the `magic range` of twisted bilayer graphene is larger than previously expected

In materials science and quantum physics, flat bands and correlated behaviors within the `magic angle` twisted bilayer graphene (tBLG) has sparked significant interest, although many of its properties face intense debate. In a new report published in Science Advances, Emilio Codecido and colleagues in the departments of physics and materials science in the U.S. and Japan observed both superconductivity and a Mott-like insulator state in a tBLG device with a twist angle approximating 0.93 degrees. This angle was 15 percent smaller than the magic angle computed (~ 1.1) in previous studies. The study revealed the `magic` range of tBLG to be larger than previously expected. The work provided a wealth of new information to decipher the strong quantum phenomena within tBLG devices for applications in quantum physics.
