  2. 16-cell honeycomb - Wikipedia

    en.wikipedia.org/wiki/16-cell_honeycomb

    The vertex arrangement of the 16-cell honeycomb is called the D 4 lattice or F 4 lattice. [2] The vertices of this lattice are the centers of the 3-spheres in the densest known packing of equal spheres in 4-space; [3] its kissing number is 24, which is also the same as the kissing number in R 4, as proved by Oleg Musin in 2003.

  3. Particle in a one-dimensional lattice - Wikipedia

    en.wikipedia.org/wiki/Particle_in_a_one...

    When talking about solid materials, the discussion is mainly around crystals – periodic lattices. Here we will discuss a 1D lattice of positive ions. Assuming the spacing between two ions is a, the potential in the lattice will look something like this: The mathematical representation of the potential is a periodic function with a period a.

  4. Topological vector lattice - Wikipedia

    en.wikipedia.org/wiki/Topological_vector_lattice

    In mathematics, specifically in functional analysis and order theory, a topological vector lattice is a Hausdorff topological vector space (TVS) that has a partial order making it into vector lattice that possesses a neighborhood base at the origin consisting of solid sets. [1]

  5. Rectangular lattice - Wikipedia

    en.wikipedia.org/wiki/Rectangular_lattice

    The rectangular lattice and rhombic lattice (or centered rectangular lattice) constitute two of the five two-dimensional Bravais lattice types. [1] The symmetry categories of these lattices are wallpaper groups pmm and cmm respectively.

  6. Su–Schrieffer–Heeger model - Wikipedia

    en.wikipedia.org/wiki/Su–Schrieffer–Heeger_model

    In condensed matter physics, the Su–Schrieffer–Heeger (SSH) model or SSH chain is a one-dimensional lattice model that presents topological features. [1] It was devised by Wu-Pei Su, John Robert Schrieffer, and Alan J. Heeger in 1979, to describe the increase of electrical conductivity of polyacetylene polymer chain when doped, based on the existence of solitonic defects.

  7. Optical lattice - Wikipedia

    en.wikipedia.org/wiki/Optical_lattice

    A 1D optical lattice is formed by two counter-propagating laser beams of the same polarization. The beams will interfere, leading to a series of minima and maxima separated by λ / 2 {\displaystyle \lambda /2} , where λ {\displaystyle \lambda } is the wavelength of the light used to create the optical lattice.

  9. Lattice model (physics) - Wikipedia

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

    Lattices such as this are used - for example - in the Flory–Huggins solution theory In mathematical physics , a lattice model is a mathematical model of a physical system that is defined on a lattice , as opposed to a continuum , such as the continuum of space or spacetime .
