Princeton University scientists have found 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 material.
Fractals are self-repeating patterns that occur on different length scales and can be seen in nature in a variety of settings, including snowflakes, ferns and coastlines.
The research may not yield any practical applications, at least not right away, the work uncovered features of Hofstadter’s spectrum that are of interest to fundamental physics research.
The researchers found that theoretical modeling of the spectrum improved if they included phenomena that are related to electrons interacting with each other.
