摘要：
We explore the theoretical possibility of extending the usual squeezed state to those produced by nonlinear singlemode squeezing operators. We derive the wave functions of exp [-(ig/2) (root 1 - (XP)-P-2 + P root 1 - X-2)]vertical bar 0 > in the coordinate representation. A new operator's disentangling formula is derived as a by-product.
