Superconducting Twisted Bilayer Graphene—Magic not Needed?


A new study shows that superconductivity in twisted bilayer graphene can exist away from the magic angle when coupled to a two-dimensional semiconductor. "Our observations were quite unexpected. It implies that we only scratched the surface of graphene twistronics. These are exciting times for the field," says Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science.

Finding the Magic in the Magic Angle


Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science, and colleagues have built upon, the discovery of the "magic angle" for stacked sheets of graphene, by generating an image of the atomic structure and electronic properties of magic angle-twisted graphene, yielding new insight into the phenomenon by offering a more direct way of studying it. They have developed a new method of creating samples of magic angle-twisted graphene that can be used to align the two sheets of graphene very precisely while leaving it exposed for direct observation.

Engineering Nanodevices to Store Information the Quantum Way


Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science, is interested in creating a device that could harness the power of entangled particles within a usable technology. A large part of his research is focused on finding ways to store and process quantum information. Quantum information is very fragile and even the smallest amount of external noise messes up quantum states. There are various schemes that tackle this problem and postpone decoherence, but the one that he is most interested in involves Majorana fermions. Relatively recently theorists figured out how to engineer these particles in the lab. Nadj-Perge explains, “it turns out that, under certain conditions, when you combine certain materials and apply high magnetic fields at very cold temperatures, electrons will form a state that looks exactly as you would expect from Majorana fermions. Furthermore, such engineered states allow you to store quantum information in a way that postpones decoherence.” [Caltech story]
