Wave functions of a new kind of nonlinear single-mode squeezed state
Hong-Yi Fan, Cheng Da, Junhua Chen · Chinese Physics B · 2014
We explore the theoretical possibility of extending the usual squeezed state to those produced by nonlinear single-mode squeezing operators. We derive the wave functions of exp[−(i g /2)( P + P )|0⟩ in the coordinate representation. A new operator's disentangling formula is derived as a by-product.
