Lattice


In metaphysics, the word lattice is synonymous with Matrix, Grids, spiraling DNA, consciousness, linked to Jacob's Ladder As consciousness evolves, we move through the lattice, to find the answers that guide our spiritual destiny. In so doing, we wish to activate our DNA and move our conscious awareness into higher frequency experiences.

In physics, a lattice model is a physical model that is defined on a lattice, as opposed to the continuum of space or spacetime. Lattice models originally occurred in the context of condensed matter physics, where the atoms of a crystal automatically form a lattice. Currently, lattice models are quite popular in theoretical physics, for many reasons. Some models are exactly solvable, and thus offer insight into physics beyond what can be learned from perturbation theory. Lattice models are also ideal for study by the methods of computational physics, as the discretization of any continuum model automatically turns it into a lattice model.

Examples of lattice models in condensed matter physics include the Ising model, the Potts model, the XY model, the Toda lattice. The exact solution to many of these models (when they are solvable) includes the presence of solitons. Techniques for solving these include the inverse scattering transform and the method of Lax pairs. The solution of these models has given insights into the nature of phase transitions, magnetization and scaling behavior, as well as insights into the nature of quantum field theory.

Lattice models frequently occur as an approximation to a continuum theory, either to give an ultraviolet cutoff to the theory to prevent divergences or to perform numerical computations. An example of a continuum theory that is widely studied by lattice models is the QCD lattice model, a discretization of quantum chromodynamics. More generally, lattice gauge theory and lattice field theory are areas of study.
