Lattice (order) — See also: Lattice (group) The name lattice is suggested by the form of the Hasse diagram depicting it. Shown here is the lattice of partitions of a four element set {1,2,3,4}, ordered by the relation is a refinement of . In mathematics, a… … Wikipedia
Lattice (group) — A lattice in the Euclidean plane. In mathematics, especially in geometry and group theory, a lattice in Rn is a discrete subgroup of Rn which spans the real vector space Rn. Every lattice in Rn … Wikipedia
Lattice model (physics) — For other meanings, see lattice model (disambiguation) 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 … Wikipedia
Lattice phase equaliser — A lattice phase equaliser or lattice filter is an example of an all pass filter. That is, the attenuation of the filter is constant at all frequencies but the relative phase between input and output varies with frequency. The lattice filter… … Wikipedia
Modular lattice — Hasse diagram of N5, the smallest non modular lattice. In the branch of mathematics called order theory, a modular lattice is a lattice that satisfies the following self dual condition: Modular law x ≤ b implies… … Wikipedia
Fundamental pair of periods — In mathematics, a fundamental pair of periods is an ordered pair of complex numbers that define a lattice in the complex plane. This type of lattice is the underlying object with which elliptic functions and modular forms are defined. Although… … Wikipedia
Cooper pair — In condensed matter physics, a Cooper pair or BCS pair is two electrons (or other fermions) that are bound together at low temperatures in a certain manner first described in 1956 by American physicist Leon Cooper.[1] Cooper showed that an… … Wikipedia
Niemeier lattice — In mathematics, a Niemeier lattice is one of the 24 positive definite even unimodular lattices of rank 24, which were classified by Hans Volker Niemeier (1973). Venkov (1978) gave a simplified proof of the classification. Witt (1941) has a… … Wikipedia
Chasman-Green lattice — Renate Chasman and G. Kenneth Green were scientists at the U.S. Department of Energy’s Brookhaven National Laboratory in Upton, NY, who invented a special periodic arrangement of magnetic elements a so called magnetic lattice – to provide… … Wikipedia
Chasman–Green lattice — The Chasman–Green lattice, also known as a double bend achromat lattice (DBA lattice), is a special periodic arrangement of magnets designed by Renate Chasman and G. Kenneth Green of Brookhaven National Laboratory in the mid 1970s. These lattices … Wikipedia
Cooper electron pair — A Cooper (electron) pair is a quasi bound state of a pair of two electrons in a superconducting material. The composite entity behaves as a particle, with zero spin and charge twice that of an electron. Cooper pairs carry the current in a… … Wikipedia
