陽に解かずに準位の交差を調べる
誰かこれを読んで面白いかどうか教えて．
- Is there a way to predict the total number of (avoided) crossings in the spectrum?
- Is there a systematic way to locate all the (avoided) crossings in the spectrum?
- Is there a way to identify the physical mechanisms responsible for the occurrence of (avoided) crossings in the spectrum?
- Can the degeneracies - if any - in the spectrum be thought of as crossings?
- Sometimes the crossings are hard to discern in the spectrum - can they be visualized in a clearer way?
In this article we employ an algebraic method that addresses these basic questions as well as some others. It allows for a simple but systematic approach to (avoided) crossings. In describing this approach we reintroduce to the study of (avoided) crossings a very useful but perhaps neglected mathematical tool, the discriminant.
