Time dependent perturbation(determination of order)

Click For Summary
SUMMARY

The discussion focuses on the challenges of determining order in time dependent perturbation theory, specifically noting the absence of a lambda parameter that is present in time independent perturbation theory. Participants express confusion regarding the methodology for establishing order without this parameter. A reference to a lecture by M. Moore from Michigan State University is provided as a potential resource for further clarification on this topic.

PREREQUISITES
  • Understanding of quantum mechanics principles

I have a question about time dependent perturbation.
In time dependent perturbation, unlike time independent perturbation, there is no lamda which is used for comparing order.
So, I`m confused how can I determine order.
Is there any explanation which use lambda or some other method for transparent order comparision?
