Question
Which term in the perturbation series represents the unperturbed solution to the system?
OPTIONS
∣Ψ(2)(t)⟩
∣Ψ(0)(t)⟩
∣Ψ(t)⟩
∣Ψ(1)(t)⟩
Solution
To determine which term in the perturbation series represents the unperturbed solution to the system, we need to understand the meaning of each term in the series.
In a perturbation series, the terms represent corrections to the unperturbed solution. The unperturbed solution, denoted as ∣Ψ(0)(t)⟩, represents the solution to the system without any perturbation or external influence. It is the starting point from which the perturbation series is built.
Therefore, the term that represents the unperturbed solution to the system is ∣Ψ(0)(t)⟩.
