I am interested in Schrodinger equation with tempor. element

SUMMARY

The discussion focuses on the Schrödinger equation with a temporal element and the complexities of calculating and normalizing probability in a three-variable coordinate system over time. The solution Ae^i(kx - wt) is identified as non-normalizable, leading to the necessity of understanding Rigged Hilbert Spaces for rigorous treatment. The conversation emphasizes the importance of a solid grasp of Fourier Transforms to avoid convergence issues, particularly for physicists and applied mathematicians.

I am interested in Schrödinger equation with the temporal element and the calculation of the probability when its depend on 3 variable coordinate and time? How to calculate it and norm it? Probability = (integral x,y,z...0 to infinity) * (integral t...0 to infinity)=1 ?

Hi

Ae^i(kx - wt) in suitable units is a solution and is not normalizeable.

So you can't always normalize it. The solution lies in what's called Rigged Hilbert Spaces.

At the intuitive level you consider it as an approximation to one that is ie assuming a finite universe at some very large distance it is zero. But rigorously it requires what I said - Rigged Hilbert Spaces.

As a warm-up up I highly recommend the following book:

All physicists, and indeed applied mathematicians need to know this stuff. It's worth it for its treatment of Fourier Transforms alone - otherwise you get bogged down in issues of convergence, providing of course you want to have at least a reasonable level of rigor and not hand-wavy - which IMHO is the same as the intuitive view I gave before. Its OK to start with but as you progress you will want a better understanding.

Thanks
Bill
