Nonlinear harmonic oscillators

Journal of Physics A: Mathematical and General, 2002
This paper deals with the existence of assembles of an arbitrary number of complex oscillators, or equivalently of an arbitrary even number of real oscillators, characterized by Newtonian equations of motion (``acceleration equal force'') with one-body velocity-dependent linear forces and many-body velocity-independent cubic forms, all the nonsingular ...

Nonadiabatic Harmonic Oscillator

The Physics of Fluids, 1970
Nonadiabatic changes in the action integral are estimated for the special case of even ω(t) by using a steepest-descent method to evaluate an integral of Vandervoort. The results are found to be in good agreement with a numerical example.

Linked Harmonic Oscillators

SIAM Journal on Applied Mathematics, 1973
The normal modes of oscillation of a circular array of linked harmonic oscillators are considered from a variety of points of view, and a representation of the oscillations of an infinite array in terms of contour integrals is given.

The harmonic oscillator

1993
This chapter is the closest in these notes to what is usually called “Quantum Mechanics”. The present version is considerably shorter than the original French. It thus becomes more obvious that its main topic is not really elementary quantum mechanics, but rather elementary Fock space, and the quantum analogue of finite dimensional Gaussian random ...

Weakly Coupled Harmonic Oscillators

SIAM Journal on Applied Mathematics, 1974
Sufficient conditions are given here for the existence and stability of a possibly infinite sequence of isolated periodic solutions of the nonautonomous system of differential equations \[ \ddot y_k + \omega _k^2 y_k = \mu f_k \left(y_1 , \cdots ,y_n ,\dot y_1 , \cdots ,\dot y_n ,t\right) \], where $0 < \mu \ll 1,k = 1, \cdots ,n$.
