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
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.
