摘要: A general definition of ``cosine'' and ``sine'' operators, C S, for harmonic oscillator phase is proposed its consequences examined. An important feature the spectral analysis ``chain sequence'' condition which ensures that S have unit norm. The (nonunitary) operator U = + iS shown to be an annihilation‐type whose properties bear a remarkable analogy those standard annihilation operator, although spectrum fills circle rather than entire complex plane. Statistical eigenstates are discussed briefly.
