    "abstract": "We study the phenomena at the overlap of quantum chaos and nonclassical\nstatistics for the time-dependent model of nonlinear oscillator. It is shown in\nthe framework of Mandel Q-parameter and Wigner function that the statistics of\noscillatory excitation number is drastically changed in order-to chaos\ntransition. The essential improvement of sub-Poissonian statistics in\ncomparison with an analogous one for the standard model of driven anharmonic\noscillator is observed for the regular operational regime. It is shown that in\nthe chaotic regime the system exhibits the range of sub- and super-Poissonian\nstatistics which alternate one to other depending on time intervals. Unusual\ndependence of the variance of oscillatory number on the external noise level\nfor the chaotic dynamics is observed.",
