What Do You Mean By Time Independent Perturbation Theory? Time-independent perturbation theory is an approximation scheme that applies in the following context: we know the solution to the eigenvalue problem of the Hamiltonian H0, and we want the solution to H = H0 +H1 where H1 is small compared to H0 in a sense to

What Is First Order Perturbation Theory?

What Is First Order Perturbation Theory? The first-order perturbation equation includes all the terms in the Schrödinger equation ˆHψ=Eψ that represent the first order approximations to ˆH,ψ and E. This equation can be obtained by truncating ˆH,ψ and E after the first order terms. What is meant by perturbation theory? In mathematics and applied mathematics,
