Recently, scientists at the University of California, Berkeley, have made a major breakthrough in the field of quantum physics. By utilizing the Moiré surface, they have successfully been able to capture the elusive Hofstadter butterfly - an energy-level pattern that has long eluded physicists. This breakthrough could lead to a deeper understanding of electronic properties and pave the way for the development of new materials. The Moiré surface is a type of superlattice that is formed when two flat surfaces are misaligned with each other. By tweaking the misalignment, the UC Berkeley scientists were able to pin down the Hofstadter butterfly in a 2D electron system. This could lead to a better understanding of the electronic properties of materials that could lead to the development of new materials.
