Anharmonic oscillators - Open Access .click

Physical Review D, 1990
An analysis of the anharmonic fermion oscillator, possessing an $\mathrm{Sp}(2)\ifmmode\times\else\texttimes\fi{}\mathrm{O}(N)$ symmetry, is presented. The complete solution is given for $N=2 \mathrm{and} 3$, and the general features for arbitrary $N$ are spelled out.

Anharmonic oscillators revisited

International Journal of Non-Linear Mechanics, 1985
A large class of anharmonic oscillators represented by the Hamiltonian $H(p,q)=(1/2)p^ 2+(1/2)q^ 2+\lambda q^{\alpha}$ ($\alpha$ integer $>2)$ is considered. Owing to an integration technique using the Lagrange-Bürmann theorem the solution of the motion equation is given in terms of series of Gauss hypergeometric functions.
