111Flavour (particle physics) — In particle physics, flavour or flavor (see spelling differences) is a quantum number of elementary particles related to their weak interactions. In the electroweak theory this symmetry is gauged, and flavour changing processes exist. In quantum… …

113Burau representation — In mathematics the Burau representation is a representation of the braid groups. The Burau representation has two common and near equivalent formulations, the reduced and unreduced Burau representations. Definition Consider the braid group B n to …
114Clifford theory — For the result about curves, see Clifford s theorem on special divisors. In mathematics, Clifford theory, introduced by Clifford (1937), describes the relation between representations of a group and those of a normal subgroup. Alfred H. Clifford… …
115Borel functional calculus — In functional analysis, a branch of mathematics, the Borel functional calculus is a functional calculus (that is, an assignment of operators from commutative algebras to functions defined on their spectrum), which has particularly broad… …
116Euler angles — The Euler angles were developed by Leonhard Euler to describe the orientation of a rigid body (a body in which the relative position of all its points is constant) in 3 dimensional Euclidean space. To give an object a specific orientation it may… …
117Killing form — In mathematics, the Killing form, named after Wilhelm Killing, is a symmetric bilinear form that plays a basic role in the theories of Lie groups and Lie algebras. In an example of Stigler s law of eponymy, the Killing form was actually invented… …
118Hamiltonian (quantum mechanics) — In quantum mechanics, the Hamiltonian H is the observable corresponding to the total energy of the system. As with all observables, the spectrum of the Hamiltonian is the set of possible outcomes when one measures the total energy of a system.… …
119Quantum harmonic oscillator — The quantum harmonic oscillator is the quantum mechanical analogue of the classical harmonic oscillator. It is one of the most important model systems in quantum mechanics because an arbitrary potential can be approximated as a harmonic potential …
