nondegenerate state
1Quantum state — In quantum physics, a quantum state is a mathematical object that fully describes a quantum system. One typically imagines some experimental apparatus and procedure which prepares this quantum state; the mathematical object then reflects the… …
2Measurement in quantum mechanics — Quantum mechanics Uncertainty principle …
3Gelfand-Naimark-Segal construction — In functional analysis, given a C* algebra A , the Gelfand Naimark Segal construction establishes a correspondence between cyclic * representations of A and certain linear functionals on A (called states ). The correspondence is shown by an… …
4Spinor — In mathematics and physics, in particular in the theory of the orthogonal groups (such as the rotation or the Lorentz groups), spinors are elements of a complex vector space introduced to expand the notion of spatial vector. Unlike tensors, the… …
5K·p perturbation theory — In solid state physics, k·p perturbation theory is an approximation scheme for calculating the band structure (particularly effective mass) and optical properties of crystalline solids. It is pronounced k dot p , and is also called the k·p method …
6Adiabatic theorem — The adiabatic theorem is an important concept in quantum mechanics. Its original form, due to Max Born and Vladimir Fock (1928),cite journal |author=M. Born and V. A. Fock |title=Beweis des Adiabatensatzes |journal=Zeitschrift für Physik A… …
7White dwarf — For other uses, see White dwarf (disambiguation). Image of Sirius A and Sirius B taken by the Hubble Space Telescope. Sirius B, which is a white dwarf, can be seen as a faint pinprick of light to the lower left of the much brighter Sirius A …
8Paranoia — (See also Erotomania; Folie à Deux; French Chronic Delusional States; Psychosis: Emergence.) Paranoia means a fixed false belief formed via logical reasoning (making it distinct from schizophrenia); aside from his delusional system, the… …
9Self-adjoint operator — In mathematics, on a finite dimensional inner product space, a self adjoint operator is one that is its own adjoint, or, equivalently, one whose matrix is Hermitian, where a Hermitian matrix is one which is equal to its own conjugate transpose.… …
10p-n junction — A silicon p–n junction with no applied voltage. A p–n junction is formed at the boundary between a P type and N type semiconductor created in a single crystal of semiconductor by doping, for example by ion implantation, diffusion of dopants, or… …
