摘要: 利用自洽平均值近似方法计算了带坐标3次方项和带坐标4次方项的非线性谐振子的能量本征值,并且分别与微扰近似方法求得的结果相对比,在小参数的情况下,其结果比微扰近似方法误差更小、更精确.

关键词: 自洽平均值近似法, 非线性谐振子, 能量本征值

Abstract: By utilizing the approximation method of self-consistent average value, the eigenvalue is given for nonlinear harmonic oscillators with third power or fourth power potential. The results coincide with the ones derived from perturbation method.

Key words: approximation of self-consistent average, nonlinear harmonic oscillator, eigenvalue
