Conformal field theory (CFT) is a branch of theoretical physics that studies the dynamics of fields in two-dimensional spacetimes that are invariant under conformal transformations. These transformations preserve angles but not necessarily distances, allowing for a wide range of applications in various areas of physics, including string theory, condensed matter physics, and statistical mechanics. CFT has proven to be a powerful tool in understanding the symmetry and universality of critical phenomena in diverse systems, as well as providing insights into the behavior of quantum field theories at critical points. The study of CFT has led to significant advances in theoretical physics and continues to be an active area of research.
