    "abstract": "From the photon-added one-photon nonlinear coherent states $a^{\\dagger\nm}|\\alpha,f\u003e$, we introduce a new type of nonlinear coherent states with\nnegative values of $m.$ The nonlinear coherent states corresponding to the\npositive and negative values of $m$ are shown to be the result of nonunitarily\ndeforming the number states $|m\u003e$ and $|0\u003e$, respectively. As an example, we\nstudy the sub-Poissonian statistics and squeezing effects of the photon-added\ngeometric states with negative values of $m$ in detail. Finally we investigate\nthe photon-added two-photon nonlinear coherent states and find that they are\nstill the two-photon nonlinear coherent states with certain nonlinear\nfunctions.",
