Beyond the Schwinger boson representation of the su(2)-algebra. II -- Some theoretical features of new boson representation and connections to the other boson representations
arXiv:1409.3628
Abstract
Concerning the new boson representation presented in Part I, it is proved that this representation obeys the su(2)-algebra in a certain subspace in the whole boson space constructed by the Schwinger boson representation of the su(1,1)-algebra. Some other problems related to this representation are discussed.
