... The latest LEP experiments at CERN suggest that the electron charge is confined within a region of radius Re < 10−19 m. Nevertheless, the quantum mechanical behaviour of the electron appears at distances of the order of its Compton wavelength λC = h̄/mc  10−13 m, which is six orders of magnitude la ...

For simple model problems it would be more appropriate to base a quantum-classical separation on normal mode coordinates in order to minimize the effect of the quantum coordinates on the classical ones, and vice versa ...

History of quantum field theory

In particle physics, the history of quantum field theory starts with its creation by Paul Dirac, when he attempted to quantize the electromagnetic field in the late 1920s. Major advances in the theory were made in the 1950s, and led to the introduction of quantum electrodynamics (QED). QED was so successful and ""natural"" that efforts were made to use the same basic concepts for the other forces of nature. These efforts were successful in the application of gauge theory to the strong nuclear force and weak nuclear force, producing the modern standard model of particle physics. Efforts to describe gravity using the same techniques have, to date, failed. The study of quantum field theory is alive and flourishing, as are applications of this method to many physical problems. It remains one of the most vital areas of theoretical physics today, providing a common language to many branches of physics.
