"Fractional Electron Behavior Discovered in Graphene"

Physicists at MIT have observed the fractional quantum anomalous Hall effect in five layers of graphene, a material that was not expected to exhibit this effect. This phenomenon, where electrons split into fractions of their total charge, is a rare and exotic electronic state that could have implications for building resilient quantum computers. The researchers found that the stacked structure of graphene inherently provides the right conditions for electrons to exhibit fractional charge without the need for an external magnetic field. This discovery opens up possibilities for more robust quantum computing and further exploration of rare electronic states in multilayer graphene.
