| 英文摘要 | The generalized inverses of q-boson operators denoted by (a) over cap (dagger -1)(q) and (a) over cap (-1)(q) are introduced via their acting on the q-number states. The even and odd number eigenstates of two-photon operators (a) over cap (dagger -1)(q)(a) over cap (q), and (a) over cap (q)(a) over cap (dagger -1)(q) are constructed. It is shown that these states can show quantum-squeezing. However, their even number states always show quantum-antibunching, while their odd number states always show quantum-bunching, This result is different from that in recent paper (C.L. Mehta, A.K. Roy and G.M. Saxena, Phys. Rev. A46 (1992) 1565) where the odd number eigenstates of operators (a) over cap (dagger -1)(q)(a) over cap (q) and (a) over cap (q)(a) over cap (dagger -1)(q) with q = 1 show bunching for some parameter values and antibunching for other parameter values. |
