摘要
A formalism for the number-phase quantization, based on the doubting of the degrees of freedom, is studied from a group-theoretical viewpoint. The so-called relative number states are shown to be a standard basis of unitary irreducible representations of both SU(2) and SU(1, 1). The algebraic meaning of the relevant operators is elucidated and their eigenstates are constructed. As an example, the dynamics of the quantum-damped harmonic oscillator is worked out.
