In atomic physics, close coupling is a quantum mechanics method to calculate the multi-electronic atomic and molecular structure from fine structure to hyperfine structure levels and dynamic processes including photoionization, [1] [2] collisional excitation and ionization as well as autoionization and their inverse processes.
Two coupled quantum systems can be modeled by a Hamiltonian of the form Dispersion relations for non-coupled, weakly-coupled, and strongly-coupled particles H ^ = H ^ a + H ^ b + V ^ a b {\displaystyle {\hat {H}}={\hat {H}}_{a}+{\hat {H}}_{b}+{\hat {V}}_{ab}} which is the addition of the two Hamiltonians in isolation with an added interaction ...
Whether loosely or tightly coupled, a system's performance is often reduced by message and parameter creation, transmission, translation (e.g. marshaling) and message interpretation (which might be a reference to a string, array or data structure), which require less overhead than creating a complicated message such as a SOAP message. Longer ...
This equation, called Schrödinger's equation, describes the behavior of an isolated or closed quantum system, that is, by definition, a system which does not interchange information (i.e. energy and/or matter) with another system. So if an isolated system is in some pure state |ψ(t) ∈ H at time t, where H denotes the Hilbert space of the ...
A short-coupled aircraft or close-coupled aircraft is an aircraft with a relatively short distance between the wing and empennage (tail assembly) or whatever is used to provide the force that is used to balance the aircraft along its longitudinal axis.
However, this definition has been challenged by the Gettier problem which suggests that justified true belief does not provide a complete picture of knowledge. Bias in education A real or perceived bias in the educational system. Bilingual education Has multiple definitions: education where two distinct languages are used for general teaching;
Close-coupled sedan, an obsolete type of automobile Topics referred to by the same term This disambiguation page lists articles associated with the title Close coupled .
In electronics, electric power and telecommunication, coupling is the transfer of electrical energy from one circuit to another, or between parts of a circuit. Coupling can be deliberate as part of the function of the circuit, or it may be undesirable, for instance due to coupling to stray fields.
