Heisenberg model (quantum) exhibits quasi-long range order. Heisenberg 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 spins of the magnetic systems are treated quantum mechanically. In the prototypical Ising model, defined on a "d"-dimensional lattice, at each lattice site, a spin formula_1 represents a microscopic magnetic dipole to which the magnetic moment is either up or down. Except the coupling between magnetic dipole moments, there is also a multipolar version of Heisenberg model called the multipolar exchange interaction. For quantum mechanical reasons (see exchange interaction
The Eyes of Heisenberg Pringle rated "The Eyes of Heisenberg" two stars out of four. Pringle described the book as "a provocative novel of ideas written in this author's usual style". The Eyes of Heisenberg The Eyes of Heisenberg is a 1966 science fiction novel by American writer Frank Herbert. Originally serialized as Heisenberg's Eyes in "Galaxy" magazine between June and August 1966, it was issued by Berkley in the same year. The title refers to Werner Heisenberg's uncertainty principle, here applied both on the molecular (genetic) level (producing the atypical embryo the story hinges on) and on a macroscopic, societal level.
