Lattice Boltzmann methods — (LBM) is a class of computational fluid dynamics (CFD) methods for fluid simulation. Instead of solving the Navier–Stokes equations, the discrete Boltzmann equation is solved to simulate the flow of a Newtonian fluid with collision models such as … Wikipedia
Lattice energy — Sodium chloride crystal lattice The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound. It is usually defined as the enthalpy of formation of the ionic compound from gaseous ions and as such is… … Wikipedia
Lattice gauge theory — In physics, lattice gauge theory is the study of gauge theories on a spacetime that has been discretized onto a lattice. Although most lattice gauge theories are not exactly solvable, they are of tremendous appeal because they can be studied by… … Wikipedia
Optical lattice — Simulation of an optical lattice potential. An optical lattice is formed by the interference of counter propagating laser beams, creating a spatially periodic polarization pattern. The resulting periodic potential may trap neutral atoms via the… … Wikipedia
Particle in a one-dimensional lattice — In quantum mechanics, the particle in a one dimensional lattice is a problem that occurs in the model of a periodic crystal lattice. The potential is caused by ions in the periodic structure of the crystal creating an electromagnetic field so… … Wikipedia
Particle in a one-dimensional lattice (periodic potential) — In quantum mechanics, the particle in a one dimensional lattice is a problem that occurs in the model of a periodic crystal lattice. The problem can be simplified from the 3D infinite potential barrier (particle in a box) to a one dimensional… … Wikipedia
Vortex lattice method — The Vortex lattice method, (VLM), is a numerical, Computational fluid dynamics, method used mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing, of an … Wikipedia
Reciprocal lattice — In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum… … Wikipedia
Hamiltonian lattice gauge theory — In physics, Hamiltonian lattice gauge theory is a calculational approach to gauge theory and a special case of lattice gauge theory in which the space is discretized but time is not. The Hamiltonian is then re expressed as a function of degrees… … Wikipedia
Delta potential — The delta potential is a potential that gives rise to many interesting results in quantum mechanics. It consists of a time independent Schrödinger equation for a particle in a potential well defined by a Dirac delta function in one dimension. For … Wikipedia
