In physics, a correspondence principle is any one of several premises or assertions about the relationship between classical and quantum mechanics.The physicist Niels Bohr coined the term in 1920 [1] during the early development of quantum theory; he used it to explain how quantized classical orbitals connect to quantum radiation. [2]
The correspondence principle is broadly aligned with the conflict theory approach to sociology, which originated with Karl Marx.Marx's said that there is a social class division in capitalist society, between on the one hand a small percentage of the population who are capitalists, owning the means of production, and on the other workers, who sell their labor power to the capitalists.
Nevertheless, as explained in the introduction, for states that are highly localized in space, the expected position and momentum will approximately follow classical trajectories, which may be understood as an instance of the correspondence principle. Similarly, we can obtain the instantaneous change in the position expectation value.
A heuristic postulate called the correspondence principle was introduced to quantum theory by Niels Bohr: in effect it states that some kind of continuity argument should apply to the classical limit of quantum systems as the value of the Planck constant normalized by the action of these systems becomes very small.
Correspondence principle (physics): quantum physics theories must agree with classical physics theories when applied to large quantum numbers; Correspondence principle (sociology), the relationship between social class and available education; Correspondence problem (computer vision), finding depth information in stereography
The correspondence principle is a concept in quantum theory and relativity. Correspondence principle may also refer to: Correspondence principle (sociology), correspondence between social class and available education; In public finance, the principle that identifies the places where it is beneficial to provide public goods and services
The correspondence principle is that the stability of equilibrium for a system (such as a market or economy) implies meaningful theorems in comparative statics. Alternatively, the hypothesis of stability imposes directional restrictions on the movement of the system (Samuelson, pp. 258, 5).
The Kramers–Heisenberg dispersion formula is an expression for the cross section for scattering of a photon by an atomic electron.It was derived before the advent of quantum mechanics by Hendrik Kramers and Werner Heisenberg in 1925, [1] based on the correspondence principle applied to the classical dispersion formula for light.
