Landau-Ginzburg Paradigm of Topological Orders and a CFT Factory

Explore the Landau-Ginzburg paradigm for understanding topological orders and its applications in constructing conformal field theories in this seminar by Dr. Yu Zhao from Fudan University. Delve into advanced theoretical physics concepts that bridge topological quantum matter and conformal field theory, examining how the Landau-Ginzburg framework provides insights into topological phases of matter. Learn about the systematic construction of conformal field theories through what the speaker terms a "CFT factory," understanding the mathematical structures and physical principles that govern these quantum field theoretical systems. Discover the connections between topological orders, which describe exotic phases of quantum matter, and the powerful tools of conformal field theory used to analyze critical phenomena and quantum phase transitions. This presentation, part of the "Quantum field theory with boundaries, impurities, and defects" program at the Isaac Newton Institute, offers deep insights into cutting-edge research at the intersection of condensed matter physics, quantum field theory, and mathematical physics.
