Current Current density Density Wavefunction

AI Thread Summary

The discussion focuses on calculating the probability density and current density of a wavefunction using the time evolution operator. The wavefunction is expressed as Ψ(x,t) = U(t,t1) * Ψ(x,t1), but the next steps for calculating the probability and current densities remain unclear. Participants suggest expanding the list of relevant equations to include those needed for probability calculations. The conversation emphasizes the importance of understanding these concepts in quantum mechanics. Clarifying these calculations is essential for progressing in the problem.

Homework Statement: Want to find the solution of part b,c and d

Relevant Equations: time evolution operator, momentum and position operator

i have use time evolution operator to get the wavefunction at any time "t" as Ψ(x,t) = U(t,t1) * Ψ(x,t1)
but i don't know how to calculate next part of the question

Maybe it helps to enlarge your list of "relevant equations" by the probabilities asked for in (b) and for the probability density and current density in (c)...

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
