About this document
Time-Dependent Perturbation Theory by Garima Tanwar is a document available to read on EtoBox.
1) Time-dependent perturbation theory is used to deal with situations where the total Hamiltonian is the sum of an unperturbed time-independent Hamiltonian and a time-dependent perturbing Hamiltonian. 2) For simple oscillating perturbations, such as from a monochromatic electromagnetic wave, the perturbing Hamiltonian can be written as a product of a time-independent operator and an oscillating time-dependent term. 3) In first-order time-dependent perturbation theory, the probability of transitions between
