  2. Operator (physics) - Wikipedia

    en.wikipedia.org/wiki/Operator_(physics)

    An operator is a function over a space of physical states onto another space of states. The simplest example of the utility of operators is the study of symmetry (which makes the concept of a group useful in this context).

  3. Matrix element (physics) - Wikipedia

    en.wikipedia.org/wiki/Matrix_element_(physics)

    In physics, particularly in quantum perturbation theory, the matrix element refers to the linear operator of a modified Hamiltonian using Dirac notation.It is in fact referring to the matrix elements of a Hamiltonian operator which serves the purpose of calculating transition probabilities between different quantum states.

  4. Momentum operator - Wikipedia

    en.wikipedia.org/wiki/Momentum_operator

    The momentum operator can be described as a symmetric (i.e. Hermitian), unbounded operator acting on a dense subspace of the quantum state space. If the operator acts on a (normalizable) quantum state then the operator is self-adjoint. In physics the term Hermitian often refers to both symmetric and self-adjoint operators. [7] [8]

  5. Observable - Wikipedia

    en.wikipedia.org/wiki/Observable

    In physics, an observable is a physical property or physical quantity that can be measured.In classical mechanics, an observable is a real-valued "function" on the set of all possible system states, e.g., position and momentum.

  6. Energy operator - Wikipedia

    en.wikipedia.org/wiki/Energy_operator

    In quantum mechanics, energy is defined in terms of the energy operator, acting on the wave function of the system as a consequence of time translation symmetry. Definition [ edit ]

  7. Singlet state - Wikipedia

    en.wikipedia.org/wiki/Singlet_state

    Since a spin-1/2 electron transforms as a doublet under rotation, its experimental response to rotation can be predicted by using the fundamental representation of that doublet, specifically the Lie group SU(2). [2] Applying the operator to the spin state of the electron thus will always result in () (+) = (), or spin-1/2, since the spin-up and ...

  8. Position and momentum spaces - Wikipedia

    en.wikipedia.org/wiki/Position_and_momentum_spaces

    In physics and geometry, there are two closely related vector spaces, usually three-dimensional but in general of any finite dimension. Position space (also real space or coordinate space ) is the set of all position vectors r in Euclidean space , and has dimensions of length ; a position vector defines a point in space.

  9. Supercharge - Wikipedia

    en.wikipedia.org/wiki/Supercharge

    It is an example of the general notion of a charge in physics. Supercharge, denoted by the symbol Q, is an operator which transforms bosons into fermions, and vice versa. Since the supercharge operator changes a particle with spin one-half to a particle with spin one or zero, the supercharge itself is a spinor that carries one half unit of spin ...
