In order to check if a quantum particle crosses a barrier or not, isn't calculating ##|\psi(x)|^2## enough in that particular region ? Why do we need to calculate probability current density for that matter?

These lectures are more of griffit's standard lectures. Thanks for the suggestions though.

Looking for recommendatuons/suggestions. Is there any lecture note series or something like that that can help studying Jackson's Electrodynamics? Thanks in advance. For instance, Prof. S. Errede's UIUC Physics 435/436 Lecture Notes helps to study Griffith's Electrodynamics...

The first equation I have written in the original post is the equation 2.104. Sorry to reply so late.

Do I calculate something like this? ##|Ψ(x,t)|^2 = (\frac 1 {\sqrt{2\pi}} \int_{-∞}^{+∞} \phi(k)e^{i(kx - \frac {ħk^2}{2m}t)}dk)(\frac 1 {\sqrt{2\pi}} \int_{-∞}^{+∞} \phi(k)e^{-i(kx - \frac {ħk^2}{2m}t)}dk)## I don't know how to do this.

I have a problem finding ##\left|Ψ(x,t)\right|^2## from the following equation: $$Ψ(x,t) = \frac 1 {\pi \sqrt{2a}} \int_{-∞}^{+∞} \frac {\sin(ka)} k e^{i(kx - \frac {ħk^2} {2m} t)} dk$$ and tried to plot like the pic below (Source Introduction to quantum mechanics by David. J. Griffiths, 2nd...

Thanks. i didn't check this text although I have this. Since I was going through Griffith's rigorously and tried to stick to it. I will check it now.

Thanks for the reply. Some of I understand and some of I don't. Can you suggest some text to study Hermite polynomial leading to the answers?

1. I have been trying to plot wavefunctions of QHO for different states with potential energy function using excel. I followed Griffith's Quantum Mechanics, 2nd edition. I got the nature but they have same reference level. Basically I tried to draw fig2.7a (the first one) and got like the second...

Does it necessary to go through all the problems in Fundamentals of Physics by Resnick and Halliday? I really need some suggestions in this case.

I understand what kind means now--------- I am basically interested in solid state physics/materials science and engineering.

Hi Radium, Thanks for responding. I am in the physics department. I want to work in a group who does work both on experimental and theory by themselves. I want to learn the experimental physics and computation work. What do you mean by "kind" - i don't understand, sorry. If you are talking about...

Thanks Dr. Courtney. I am trying. I am a newbie. I tried to start this kind of work here at Miami University but couldn't.

Though there are several posts regarding Compuational Physics, I think my post is a little bit different from them. Currently I am doing my MS in Physics in Miami University and I am in my first year. I am searching a PhD program/group who work experimental and theoretical (computational) work...
