ASHVIN VISHWANATH is a professor of physics at Harvard University and the director of the Simons Collaboration for Ultra-Quantum Matter. He is interested in fundamental questions in condensed matter physics, including the interplay of symmetry and topology in establishing new phases of quantum matter. Vishwanath has made key contributions to the theory of deconfined quantum criticality, the classification of topological phases in crystals and in the presence of strong interactions, and to the rapidly evolving field of moiré materials. Several theoretical predictions made by Vishwanath and his group have guided and been validated by experiments, including skyrmion lattices in helical magnets, Fermi-arc surface

states of Weyl semimetals, topological modes in dislocations, and a new magic-angle graphene superconductor in alternating-twist trilayer graphene. His contributions have been recognized by the Europhysics award; Sloan, Guggenheim, and APS fellowships, and, in 2021, election to the American Academy of Arts & Sciences.
