Structure of quantum field theory
General principles that constrain quantum field theories, including anomalies, conformal symmetry, dualities, and the irreversibility of renormalization group flows.
Zohar
Komargodski
My interests center on quantum field theory and its applications across fundamental physics.
Professor at the
Simons Center for Geometry and Physics

Research
Fundamental questions, concrete consequences.
Defects and extended operators
Line and surface defects, their entropy and renormalization group behavior, and the ways defects reveal new phases and symmetries.
Connections across physics
Applications of field-theoretic ideas to particle physics, statistical and condensed-matter systems, topological interactions, and quantum gravity.
