The electrons in a twisted piece of graphene show a strange repeating pattern first predicted in 1976, but never directly ...

A quantum version of a fractal pattern, known as "Hofstadter's butterfly," has long been predicted, but the new study marks the first time it has been directly observed experimentally in a real ...

Researchers observed a long-predicted fractal energy pattern in twisted carbon materials, confirming quantum theories.

The image shows a quantum version of a fractal pattern, known as “Hofstadter’s butterfly,” which has long been predicted, but the new study marks the first time it has been directly observed ...
