Research Abstract

In the two-level adiabatic transition probability with a small gap, we show how "turning points" and "Stokes lines", which are characterized by the so-called avoided crossings, affect the asymptotic behavior of the transition probability. The results gave us a great benefit for the future problems which include many turning points of higher degree.
