What Does OPE Stand For?
OPE stands for Operator Product Expansion
OPE, or Operator Product Expansion, is a mathematical framework used in quantum field theory to express an interacting field operator as a sum of products of local operators. This technique enables the analysis of correlation functions and simplifies the calculations of physical observables by relating them to simpler, well-understood quantities. OPE plays a crucial role in various aspects of theoretical physics, including the study of critical phenomena and scattering amplitudes, facilitating the understanding of complex interactions in quantum systems.
