Abstract
By use of a Jordan-Wigner transformation, the one-dimensional Hubbard model for an itinerant magnet is expressed as an anisotropic Heisenberg model on a double chain with two- and three-spin interactions. The limiting cases—(i) free electron, (ii) strong correlation, and (iii) zero-hopping rate—are briefly examined in the spin representation.Keywords
