With a simple twist, a ‘magic’ material is now the big thing in physics

quantamagazine.org
  • MIT physicists discovered ‘warm’ superconductivity, among other exciting characteristics, in two joined layers of graphene.
  • The extraordinary results were produced by finding the ‘magical’ angle to twist one layer - exactly 1.1°.
  • In 2007 it was suggested that pressing two misaligned layers of graphene could produce interesting effects.
  • Over 10 years later the theory is now confirmed by a paper that virtually created a new, currently exploding field - ‘twistronics’.
  • It is a huge milestone for studying superconductivity.
