Optical theorem — In physics, the optical theorem is a general law of wave scattering theory, which relates the forward scattering amplitude to the total cross section of the scatterer. It is usually written in the form where f(0) is the scattering amplitude with… … Wikipedia
Bell's theorem — is a theorem that shows that the predictions of quantum mechanics (QM) are not intuitive, and touches upon fundamental philosophical issues that relate to modern physics. It is the most famous legacy of the late physicist John S. Bell. Bell s… … Wikipedia
Unitarity (physics) — In quantum physics, unitarity means that the sum of probabilities of all possible outcome of any event is always 1. This is necessary for the theory to be consistent.This implies that the operator which describes the progress of a physical system … Wikipedia
Eigendecomposition of a matrix — In the mathematical discipline of linear algebra, eigendecomposition or sometimes spectral decomposition is the factorization of a matrix into a canonical form, whereby the matrix is represented in terms of its eigenvalues and… … Wikipedia
LSZ reduction formula — In quantum field theory, the LSZ reduction formula is a method to calculate S matrix elements (the scattering amplitudes) from the time ordered correlation functions of a quantum field theory. It is a step of the path that starts from the… … Wikipedia
