D. Zappala'

摘要:

利用在适当的时间调节器下得到的二阶重整化群微分展开式,计算了量子力学双阱基态和第一激发态之间的能隙.在强耦合和弱耦合两种情况下,得到了与精确结果一致的结果。

英文摘要:

The gap between ground and first excited state of the quantum-mechanical double well is calculated using the Renormalization Group equations to the second order in the derivative expansion, obtained within a class of proper time regulators. Agreement with the exact results is obtained both in the strong and weak coupling regime.
