Reflection Time Difference as a probe of S-matrix Zeroes in Chaotic Resonance Scattering

Published 2019-08-19Version 1

Motivated by recent interest in the zeroes of S-matrix entries in the complex energy plane, I use the Heidelberg model of resonance scattering to introduce the notion of Reflection Time Difference which is shown to play the same role for the {\it zeroes} as the Wigner time delay plays for the S- matrix {\it poles}.

Comments: The text is based on the presentation at the 9th Workshop on Quantum Chaos and Localization Phenomena, May 25--26, 2019, Warsaw, Poland
