- W2054760504 abstract "An approximate, variational method for the study of the generalized anharmonic oscillator $frac{{p}^{2}}{2m}+frac{m{ensuremath{omega}}^{2}{x}^{2}}{2}+ensuremath{lambda}V(x)$ is presented, $V(x)$ representing a broad class of even functions of the coordinate which admits a series expansion. The idea of the method is to introduce into the unperturbed oscillator states the correlations due to the presence of the anharmonic term via a unitary operator ${e}^{istackrel{^}{F}}$ which is determined by the variational principle. Applications to the special case $ensuremath{lambda}{x}^{2m}$ are made, and the results are compared with those obtained with different exact treatments." @default.
