Perturbation theory (quantum mechanics) — In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a … Wikipedia

Perturbation theory — This article describes perturbation theory as a general mathematical method. For perturbation theory as applied to quantum mechanics, see perturbation theory (quantum mechanics). Perturbation theory comprises mathematical methods that are used to … Wikipedia
Exchange interaction — In physics, the exchange interaction is a quantum mechanical effect without classical analog which increases or decreases the expectation value of the energy or distance between two or more identical particles when their wave functions overlap.… … Wikipedia
Quartic interaction — In quantum field theory, a quartic interaction is a theory about a scalar field phi; which contains an interaction term phi^4, and is considered by many teachers and students to be the simplest example of interacting fields. This theory consists… … Wikipedia
N-Electron Valence state Perturbation Theory — In quantum chemistry, N Electron Valence state Perturbation Theory (NEVPT) is a perturbative treatment applicable to multireference CASCI type wavefunctions. It can be considered as a generalization of the well known second order Møller Plesset… … Wikipedia
K·p perturbation theory — In solid state physics, k·p perturbation theory is an approximation scheme for calculating the band structure (particularly effective mass) and optical properties of crystalline solids. It is pronounced k dot p , and is also called the k·p method … Wikipedia
