  • WKB approach applied to 1D time-dependent nonlinear Hamiltonian oscillators
    Papamikos, Georgios ; Robnik, Marko, 1954-
    We present a simple WKB-like approach to obtain approximate analytic solutionsto a certain class of time-dependent nonlinear 1D Hamiltonian oscillators. The case of homogeneous power-law potentials ... is solved explicitlyin a closed form in the leading order. The accuracy of the approximation is surprisingly good and we illustrate it in the case of the quartic oscillator. PACS numbers: 02.30.Mv, 05.45.-a, 45.05.+x
