Anton Kapustin

Anton Kapustin is the Earle C. Anthony Professor of Theoretical Physics and Mathematics at the California Institute of Technology (Caltech). His research bridges theoretical physics and mathematics, with a focus on topological phases of matter, quantum field theory, and symmetry principles. He explores topics such as higher symmetries, anomalies in quantum systems, and the interplay between geometry and physics.

His work often integrates advanced mathematical concepts, including homotopy theory and topological invariants, to understand phenomena in condensed matter and high-energy physics. Recent studies include investigations into quantum lattice systems, non-equilibrium steady states, and the classification of topological phases. His research also addresses foundational questions in quantum mechanics and gravity, such as non-relativistic geometry and the equivalence principle.

Publications span topics like topological insulators, gauge theories, and symmetry-protected topological (SPT) phases. Kapustin collaborates across disciplines, connecting abstract mathematics with experimental physics insights. He maintains an active research group and contributes to both theoretical advancements and interdisciplinary dialogues in physics.
