In condensed matter physics, a spin glass is a magnetic state characterized by randomness, besides cooperative behavior in freezing of spins at a temperature called "freezing temperature" T f. In ferromagnetic solids, component atoms' magnetic spins all align in the same direction.

A Hopfield network (Ising model of a neural network or Ising–Lenz–Little model or Amari-Little-Hopfield network) is a spin glass system used to model neural networks, based on Ernst Ising's work with Wilhelm Lenz on the Ising model of magnetic materials.
Oct 6, 2021 · The classic example of a “spin glass,” used by the Nobel folks in citing Parisi’s work, is an alloy of non-magnetic metal with a small fraction of magnetic atoms mixed in. The energy of ...
Jun 29, 2016 · The term spin glass is first used in a paper by Anderson in 1970, Footnote 5 in analogy with structural glasses, to stress the presence of a low-temperature phase with unidentified order. He defines a formally simple model where the Hamiltonian has an explicit dependence on the disorder [ And70 ].
