SUMMARY
The discussion centers on time-dependent perturbation theory in quantum mechanics, specifically addressing the representation of perturbed wavefunctions as linear combinations of unperturbed eigenstates. Participants clarify that while the perturbation may alter energy levels, the coefficients in the linear combination represent the probability amplitudes for finding a particle in specific states. The conversation highlights the practical applications of this theory, such as calculating transition rates in systems influenced by oscillating electromagnetic fields, and emphasizes the importance of understanding the time-dependent nature of eigenfunctions in quantum systems.
