Infinite coupling magnon theory of quantum Heisenberg magnetic models of spin s | | Bang-Gui Liu

24 Oct 1997 | | Subject: | cond-mat | | Affiliation: | Institute of Physics, CAS) and Gerd Czycholl (University of Bremen | | Abstract: | An infinity magnon coupling term is introduced into the Holstein-Primakoff transformed forms of the Heisenberg ferromagnetic and antiferromagnetic models of any spin $s$ to rigorously remove the unphysical magnon states. This term makes the series expansion of the square root of the magnon operators become a finite series of magnon operator products. Under a simple Hubbard-like approximation our infinite coupling theory yields much better result than the existing spin wave theories, especially near transition temperatures. | | Source: | arXiv, cond-mat/9710261 | | Services: | Forum | Review | PDF | Favorites | |
