Conformal Field Theory (CFT)

Conformal Field Theory (CFT) is a framework in physics that studies systems where shapes and angles remain unchanged under transformations like stretching or shrinking, but not necessarily rigid motions. It focuses on understanding how particles and fields behave at critical points, such as phase transitions, by exploiting these symmetries. CFT provides powerful tools to analyze these phenomena across different dimensions, revealing deep connections between physics and mathematics, including string theory and quantum critical systems. In essence, CFT helps us understand the universal patterns and behaviors emerging in complex systems at their most symmetry-rich states.
