This boson representation is expressed in terms of two kinds of bosons with a certain positive parameter. In order to describe the case of any fermion number, third boson is introduced. Through this examination, it is concluded that this representation is well workable for the boson realization of the Lipkin model in any fermion number. | Description: | 7 pages, no figure | URI: | https://hdl.handle.net/10316/109290 | ISSN: | 2050-3911 | DOI: | 10.1093/ptep/ptv069 | Rights: | openAccess |
