本文指出，与人们的期望相反，最近在缓变量子系统中发现的规范结构或Berry连接，即使对于参数空间中对应于开路的非循环演化，也会产生可观测的效应。我们建议在μ子自旋共振和μ子自旋旋转谱中的能级交叉共振中测试这种效应。在我们的建议中，探测器或系统本身的寿命比一个绝热循环的周期短得多。
It is pointed out that, contrary to naive expectation, the gauge structure or Berry connection recently found in slowly varying quantum systems gives rise to observable effects even for noncyclic evolutions corresponding to open paths in parameter space. We propose to test such effects in muon spin resonance and in level-crossing resonance in muon-spin-rotation spectroscopy. In our proposals either the probe or the system itself has a lifetime much shorter than the period of one adiabatic cycle.
