  2. Dynamic structure factor - Wikipedia

    en.wikipedia.org/wiki/Dynamic_structure_factor

    In condensed matter physics, the dynamic structure factor (or dynamical structure factor) is a mathematical function that contains information about inter-particle correlations and their time evolution. It is a generalization of the structure factor that considers correlations in both space and time.

  3. Correlation function (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Correlation_function...

    From knowledge of elemental structure factors, one can also measure elemental pair correlation functions. See Radial distribution function for further information. Equal-time spinspin correlation functions are measured with neutron scattering as opposed to x-ray scattering. Neutron scattering can also yield information on pair correlations ...

  4. Quark model - Wikipedia

    en.wikipedia.org/wiki/Quark_model

    The 56 states with symmetric combination of spin and flavour decompose under flavor SU(3) into = , where the superscript denotes the spin, S, of the baryon. Since these states are symmetric in spin and flavor, they should also be symmetric in space—a condition that is easily satisfied by making the orbital angular momentum L = 0 .

  5. Structure factor - Wikipedia

    en.wikipedia.org/wiki/Structure_factor

    In condensed matter physics and crystallography, the static structure factor (or structure factor for short) is a mathematical description of how a material scatters incident radiation. The structure factor is a critical tool in the interpretation of scattering patterns ( interference patterns ) obtained in X-ray , electron and neutron ...

  6. Neutron scattering - Wikipedia

    en.wikipedia.org/wiki/Neutron_scattering

    Results are generally communicated as the dynamic structure factor (also called inelastic scattering law) (,), sometimes also as the dynamic susceptibility ′ ′ (,) where the scattering vector is the difference between incoming and outgoing wave vector, and is the energy change experienced by the sample (negative that of the scattered neutron).

  7. Spin–orbit interaction - Wikipedia

    en.wikipedia.org/wiki/Spin–orbit_interaction

    The spin magnetic moment of the electron is =, where is the spin (or intrinsic angular-momentum) vector, is the Bohr magneton, and = is the electron-spin g-factor. Here μ {\displaystyle {\boldsymbol {\mu }}} is a negative constant multiplied by the spin , so the spin magnetic moment is antiparallel to the spin.

  8. Electronic correlation - Wikipedia

    en.wikipedia.org/wiki/Electronic_correlation

    Dynamical correlation is the correlation of the movement of electrons and is described under electron correlation dynamics [3] and also with the configuration interaction (CI) method. Static correlation is important for molecules where the ground state is well described only with more than one (nearly-)degenerate determinant.

  9. Spin chemistry - Wikipedia

    Furthermore, the spin of each electron previously involved in the bond is conserved, [1] [3] which means that the radical-pair now formed is a singlet (each electron has opposite spin, as in the origin bond). As such, the reverse reaction, i.e. the reforming of a bond, called recombination, readily occurs.
