When a resonant photon traverses a sample of absorbing atoms, how much time do atoms spend in the excited state? Does the answer depend on whether the photon is ultimately scattered vs. transmitted? In particular, if it is not scattered, meaning that it emerges in the direction …

In the first part of this dissertation, we introduce a new numerical method for the solution of the time-dependent Schrodinger equation (TDSE) with a smooth potential, based on its reformulation as a Volterra integral equation. We present versions of the method both for periodic…
