heisenberg model
1Heisenberg model — The Heisenberg model can refer to two models in statistical mechanics:*Heisenberg model (classical), a classical nearest neighbour spin model *Heisenberg model (quantum), a model where the spins are treated quantum mechanically using Pauli… …
2Heisenberg model (quantum) — The Heisenberg model is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spin of the magnetic systems are treated quantum mechanically. In the prototypical Ising model,… …
3Heisenberg model (classical) — The Heisenberg model is the n = 3 case of the n vector model, one of the models used in statistical physics to model ferromagnetism, and other phenomena.It can be formulated as follows: take a d dimensional lattice, and a set of spins of the unit …
4Classical Heisenberg model — The Classical Heisenberg model is the n = 3 case of the n vector model, one of the models used in statistical physics to model ferromagnetism, and other phenomena. Contents 1 Definition 2 Properties 3 See also …
5Dmrg of Heisenberg model — This example presents the infinite DMRG algorithm. It is about S = 1 antiferromagnetic Heisenberg chain, but the recipe can be applied for every translationally invariant one dimensional lattice. DMRG is a renormalization group technique because… …
6Heisenberg's microscope — exists only as a thought experiment, one that was proposed by Werner Heisenberg, criticized by his mentor Niels Bohr, and subsequently served as the nucleus of some commonly held ideas, and misunderstandings, about Quantum Mechanics. Basic ideas… …
7Heisenberg, Werner — ▪ German physicist and philosopher Introduction in full Werner Karl Heisenberg born Dec. 5, 1901, Würzburg, Ger. died Feb. 1, 1976, Munich, W.Ger. German physicist and philosopher who discovered (1925) a way to formulate quantum mechanics in… …
8Heisenberg group — In mathematics, the Heisenberg group, named after Werner Heisenberg, is the group of 3×3 upper triangular matrices of the form or its generalizations under the operation of matrix multiplication. Elements a, b, c can be taken from some… …
9Majumdar–Ghosh Model — The Majumdar Ghosh model is an extension of the one dimensional quantum Heisenberg spin model in which an extra interaction is added coupling spins two lattice spacings apart such that second neighbor coupling half as strong the first. It is… …
10Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
