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]
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.
1:1 correspondence, an older name for a bijection; Multivalued function; Correspondence (algebraic geometry), between two algebraic varieties; Corresponding sides and corresponding angles, between two polygons; Correspondence (category theory), the opposite of a profunctor; Correspondence (von Neumann algebra) or bimodule, a type of Hilbert space
Erwin Schrödinger derived it as a "minimum uncertainty" Gaussian wavepacket in 1926, searching for solutions of the Schrödinger equation that satisfy the correspondence principle. [1] It is a minimum uncertainty state , with the single free parameter chosen to make the relative dispersion (standard deviation in natural dimensionless units ...
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.
According to the correspondence principle and Ehrenfest's theorem, as a system becomes larger or more massive the classical dynamics tends to emerge, with some exceptions, such as superfluidity. This is why we can usually ignore quantum mechanics when dealing with everyday objects and the classical description will suffice.
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.
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
