Time Delay and Resonance in Simple Scattering
The concept of time delay is used to understand resonances in simple scattering. In a simple model of one dimensional Stark Hamiltonian, we test this idea and show that for small field strength one has spectral concentration near the eigenvalue of the unperturbed Hamiltonian. Time-delay for the model also exhibits a similar feature.
