AI总结:

本研究探索谐振子传播子的Mehler公式的非微扰非谐修正可能,采用替代方法计算含四阶项的条件维纳测度泛函积分,对指数中积分变量的线性项做幂级数展开,给出传播子起点为零时正负频率的解析结果。

摘要:

我们发现了谐振子传播子的Mehler公式存在非微扰非谐修正的可能性。我们采用一种不同于传统微扰方法的替代方式,计算了指数项中含四阶项的条件维纳测度泛函积分。与传统微扰理论不同的是,我们将指数项中关于积分变量的线性项展开为幂级数。我们讨论了传播子起点为零的情况,并以解析形式给出了正频率和负频率下的结果。

英文摘要:

We find the possibility of the non-perturbative an-harmonic correction to Mehler's formula for propagator of the harmonic oscillator. We evaluate the conditional Wiener measure functional integral with a term of the fourth order in the exponent by an alternative method as in the conventional perturbative approach. In contrast to the conventional perturbation theory, we expand into power series the term linear in the integration variable in the exponent. We discuss the case, when the starting point of the propagator is zero. We present the results in analytical form for positive and negative frequency.
