Question:

A one-dimensional simple harmonic oscillator of angular frequency ω is acted upon by a spatially uniform but time-dependent force (not potential)image

At t = -∞, the oscillator is known to be in the ground state. Using the timedependent perturbation theory to first order, calculate the probability that the oscillator is found in the first excited state at t = +∞.

Challenge for experts: F(t) is so normalized that the impulseimage

imparted to the oscillator is always the same-that is, independent of τ; yet for r ≫ 11 w, the probability for excitation is essentially negligible. Is this reasonable? [Matrix element of x:image
