Quantum Conformal Field Theory

Quantum Conformal Field Theory (QCFT) is a branch of theoretical physics that studies systems where the laws, particularly the behavior of particles and fields, remain unchanged under scale transformations and certain types of angle-preserving (conformal) transformations. Essentially, it explores how quantum fields behave when the system looks the same at different sizes or energy scales. This framework is crucial for understanding phenomena in high-energy physics, string theory, and critical points in materials science, providing deep insights into the fundamental symmetries and structure of the universe at quantum levels.
