Categorical Tools in Low-Dimensional Quantum Field Theory - Lecture 4

Explore categorical tools essential for understanding low-dimensional quantum field theories in this fourth lecture of an eleven-part series by theoretical physics professor Jürgen Fuchs from Karlstad University. Delve into mathematical structures relevant to two-dimensional conformal field theories and topological field theories, with applications to exotic phases of matter. Learn about non-invertible symmetries through topological domain walls, string-net model variants, and correlator constructions in two-dimensional conformal field theories. Access detailed lecture notes and supplementary materials through the provided links to enhance your understanding of these advanced mathematical physics concepts. Benefit from instruction designed for audiences with diverse backgrounds in mathematics and theoretical physics, requiring only basic familiarity with algebra, representation theory, and elementary topology, though prior exposure to quantum mechanics and quantum field theory will aid in appreciating the applications.
