SUMMARY
The discussion centers on the application of time-dependent perturbation theory in quantum mechanics, specifically regarding the integration limits for calculating transition amplitudes. Users have observed discrepancies between using limits from 0 to t and from -infinity to t, leading to significantly different results. The consensus indicates that the appropriate limit depends on the context of the perturbation, with the 0 to t limit being more relevant when the perturbed field is only active for a finite duration.
