Periodic grid-like ideal structure consisting of regularly arranged elementary repeating units.
Notes:
  1. In the condensed matter physics, lattice models are currently used for modeling and theoretical studying of electric, magnetic and optical phenomena as well as materials properties. 1-Dimensional (1-D) lattice is used for modeling linear objects such as linear conjugated polymers (see Peierls distortion), 2-D and 3-D lattices for modeling planar and spatial objects, respectively.
  2. Crystal (Bravais) lattices are the most famous examples of physical 3-D lattice models.
