具有非等效真空的对称三阱:瞬时方法
Symmetric Triple Well with Non-Equivalent Vacua: Instantonic Approach
摘要:
我们表明,对于三重势阱与非等效真空,瞬子产生的低躺的能量状态的单线态和一个双重态,而不是一个三重态的相等的能量间距。我们的能量分裂公式也得到了数值验证。这种分裂性质是由于不等价真空的存在。对该方法在多井中的通用性进行了评述。
英文摘要:
We show that for the triple well potential with non-equivalent vacua, instantons generate for the low lying energy states a singlet and a doublet of states rather than a triplet of equal energy spacing. Our energy splitting formulae are also confirmed numerically. This splitting property is due to the presence of non-equivalent vacua. A comment on its generality to multi-well is presented.
