41Photon polarization — is the quantum mechanical description of the classical polarized sinusoidal plane electromagnetic wave. Individual photons are completely polarized. Their polarization state can be linear or circular, or it can be elliptical, which is anywhere in …
42Peskin-Takeuchi parameter — In particle physics, the Peskin Takeuchi parameters are a set of three measurable quantities, called S , T , and U , that parameterize potential new physics contributions to electroweak radiative corrections. They are named after physicists… …
43Coherent states in mathematical physics — Coherent states have been introduced in a physical context, first as quasi classical states in quantum mechanics, then as the backbone of quantum optics and they are described in that spirit in the article Coherent states (see also [1]). However …
44Straight razor — A straight razor with square point and a double transverse stabiliser Main article: Razor A straight razor is a razor with a blade that can fold into its handle.[1] …
45Fujikawa method — Fujikawa s method is a way of deriving the chiral anomaly in quantum field theory.Suppose given a Dirac field ψ which transforms according to a ρ representation of the compact Lie group G ; and we have a background connection form of taking… …
46Wick's theorem — is a method of reducing high order derivatives to a combinatorics problem.(Philips, 2001) It is named after Gian Carlo Wick. It is used extensively in quantum field theory to reduce arbitrary products of creation and annihilation operators to… …
47Supersymmetric quantum mechanics — In theoretical physics, supersymmetric quantum mechanics is an area of research where mathematical concepts from high energy physics are applied to the seemingly more prosaic field of quantum mechanics. IntroductionUnderstanding the consequences… …
48arts, East Asian — Introduction music and visual and performing arts of China, Korea, and Japan. The literatures of these countries are covered in the articles Chinese literature, Korean literature, and Japanese literature. Some studies of East Asia… …
49Uncertainty principle — In quantum physics, the Heisenberg uncertainty principle states that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the… …
50Spin (physics) — This article is about spin in quantum mechanics. For rotation in classical mechanics, see angular momentum. In quantum mechanics and particle physics, spin is a fundamental characteristic property of elementary particles, composite particles… …
