非等效瞬时法
The Instantonic Approach with Non-Equivalent Vacua
摘要：
本文研究了存在非等效真空的模型中的量子力学隧穿现象。为了这样一个目的，我们评估的两个最小值的潜在问题的二次波动在相应的瞬子之间的欧几里德传播。多瞬子组态的影响包括通过交替稀释气体近似。
英文摘要：
We study the quantum-mechanical tunneling phenomenon in models which include the existence of non-equivalent vacua. For such a purpose we evaluate the euclidean propagator between two minima of the potential at issue in terms of the quadratic fluctuations over the corresponding instantons. The effect of the multi-instanton configurations are included by means of the alternate dilute-gas approximation.
