Emergence in Effective Field Theories - Philsci
... An effective field theory (EFT) of a physical system is a description of the system at energies low, or distances large, compared to a given cutoff. EFTs are constructed via a process in which degrees of freedom are eliminated from a high-energy/short-distance theory. Formulating a concept of emerge ...
