| quantum field theory
The application of quantum mechanics to physical systems described by fields, such as electromagnetic fields. Quantum field theory was developed to overcome certain deficiencies in Schrödinger's equation, in particular the fact that it was not consistent with special relativity and was difficult to apply to systems involving many particles or to the creation and destruction of particles. See also quantum chromodynamics, quantum electrodynamics. |
