Periodic poling — is formation of layers with alternate orientation in a birefringent material. The domains are regularly spaced, with period in a multiple of the desired wavelength of operation. The structure is desired to achieve quasi phase matching (QPM) in… … Wikipedia
Periodic group — In group theory in mathematics, a periodic group or a torsion group is a group in which each element has finite order. All finite groups are periodic. The concept of a periodic group should not be confused with that of a cyclic group.The exponent … Wikipedia
Periodic boundary conditions — In molecular dynamics, periodic boundary conditions (PBC) are a set of boundary conditions used to simulate an effectively infinitely tiled system, usually applied to systems consisting of one or more macromolecules in a bath of explicit solvent … Wikipedia
Alternative periodic tables — are chemical element displays different from the well known Mendeleev periodic table. Several have been devised often purely for didactic reasons as not all correlations between the chemical elements are effectively captured by the standard… … Wikipedia
Magnetic field of celestial bodies — See also Earth s magnetic field The magnetic field of a rotating body of conductive gas or liquid develops self amplifying electric currents, and thus a self generated magnetic field, due to a combination of differential rotation (different… … Wikipedia
Doubly periodic function — In mathematics, a doubly periodic function is a function defined at all points on the complex plane and having two periods , which are complex numbers u and v that are linearly independent as vectors over the field of real numbers. That u and v… … 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
Ramond-Ramond field — In theoretical physics, Ramond Ramond fields are differential form fields in the 10 dimensional spacetime of type II supergravity theories, which are the classical limits of type II string theory. The ranks of the fields depend on which type II… … Wikipedia
Polymer field theory — A polymer field theory within the framework of statistical mechanics is a statistical field theory, describing the statistical behavior of a neutral or charged polymer system within the field theoretic approach.It can be derived by transforming… … Wikipedia
Stretching field — In applied mathematics, stretching fields provide the local deformation of an infinitesimal circular fluid element over a finite time interval ∆ t . The logarithm of the stretching (after first dividing by ∆ t ) gives the finite time Lyapunov… … Wikipedia
