Energy level — A quantum mechanical system or particle that is bound that is, confined spatially can only take on certain discrete values of energy. This contrasts with classical particles, which can have any energy. These discrete values are called energy… … Wikipedia
Degenerate energy level — This article is about different quantum states having the same energy. For other uses, see Degeneracy. In physics, two or more different quantum states are said to be degenerate if they are all at the same energy level. Statistically this means… … Wikipedia

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
Vibrational energy relaxation — Vibrational energy relaxation, or vibrational population relaxation, is a process in which the population distribution of molecules in vibrationally quantum states of high energy level caused by an external perturbation returns to the Maxwell… … Wikipedia

Møller-Plesset perturbation theory — (MP) is one of several quantum chemistry post Hartree Fock ab initio methods in the field of computational chemistry. It improves on the Hartree Fock method by adding electron correlation effects by means of Rayleigh Schrödinger perturbation… … Wikipedia
Chiral perturbation theory — (ChPT) is an effective field theory constructed with a Lagrangian consistent with the (approximate) chiral symmetry of quantum chromodynamics (QCD), as well as the other symmetries of parity and charge conjugation. ChPT is a theory which allows… … Wikipedia
Zero-point energy — is the lowest possible energy that a quantum mechanical physical system may have; it is the energy of its ground state. All quantum mechanical systems undergo fluctuations even in their ground state and have an associated zero point energy, a… … Wikipedia
