Recently, scientists at MIT created a stir in the field of condensed matter physics when they showed that two sheets of graphene twisted at specific angles display two emergent phases of matter. Philip Phillips, professor of condensed matter physics at the University of Illinois, says a careful review of the MIT experimental data revealed that the insulating behavior of the "magic-angle" graphene is not Mott insulation, but something even more profound -- a Wigner crystal. Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2021 budget of $8.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
