The Analytic Continuation of the Lippmann-Schwinger Eigenfunctions, and Antiunitary Symmetries
We review the way to analytically continue the Lippmann-Schwinger bras and kets into the complex plane. We will see that a naive analytic continuation leads to nonsensical results in resonance theory, and we will explain how the non-obvious but correct analytical continuation is done. We will see th...
