2Uncertainty principle — In quantum physics, the Heisenberg uncertainty principle states that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the… …
3Path integral formulation — This article is about a formulation of quantum mechanics. For integrals along a path, also known as line or contour integrals, see line integral. The path integral formulation of quantum mechanics is a description of quantum theory which… …
4Wigner D-matrix — The Wigner D matrix is a matrix in an irreducible representation of the groups SU(2) and SO(3). The complex conjugate of the D matrix is an eigenfunction of the Hamiltonian of spherical and symmetric rigid rotors. Definition Wigner D matrix Let j …
5Optical phase space — Optical phase diagram of a coherent state s distribution across phase space. In quantum optics, an optical phase space is a phase space in which all quantum states of an optical system are described. Each point in the optical phase space… …
6Dirac bracket — The Dirac bracket is a generalization of the Poisson bracket developed by Paul Dirac to correctly treat systems with second class constraints in Hamiltonian mechanics and canonical quantization. It is an important part of Dirac s development of… …
7Quantum 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 …
8Supersymmetry — In particle physics, supersymmetry (often abbreviated SUSY) is a symmetry that relates elementary particles of one spin to another particle that differs by half a unit of spin and are known as superpartners. In other words, in a supersymmetric… …
9't Hooft operator — In theoretical physics, a t Hooft operator, introduced by Gerard t Hooft in the 1978 paper On the phase transition towards permanent quark confinement is a dual version of the Wilson loop in which the electromagnetic potential A is replaced by… …
