Precise Determination of the Energy Levels of the Anharmonic Oscillator from the Quantization of the Angle Variable

B. Bacus, Y. Meurice, A. Soemadi

Using an ansatz motivated by the classical form of $e^{i\varphi }$, where $\varphi$ is the angle variable, we construct operators which satisfy the commutation relations of the creation-annihil…
