Hi Hilbert, thank you for your response. I'm still not sure if the propagator is still valid though. When the propagator is calculated directly, we employ ##\langle x|e^{-iH(t_{1}-t_{2})/\hbar}|x'\rangle##. Can we calculate it by ##\langle x|U(t_{1},t_{2})|x'\rangle##?

Hello all, I have a fundamental problem with the concept of the propagator regarding to time dependent potential. If the propagator is based on the expansion of the time evolution operator, how can it act on initial wave function in the presence of time dependent potential? You cannot use the...

Thank you. This is very helpful. I'm going to try it now.

Hello all, I need to use numbers that are greater than 10e308 in matlab. Apparently, 52 bit MATLAB does not recognize them and uses INF instead of the big number. I googled for it and only got some vague answers how to deal with it (something about file exchange...).Help! please... thanks.

Thanks, however I want to learn about its application in quantum mechanics. The books I read so far have only poor details about it. if Ill ask mathematicians about it, Ill get symbols that I wouldn't understand ;-)

Does anyone know a good book to learn about the mathematics of the resolvent? thnx, the samurai.

Hello Hasan, Although I watched it one week later... This is exactly the answer I was looking for. Thanks.

Hello marcusl, thank you for your response. Let me change the question since it doesn't really matter if it is in MATLAB or not. If you are doing Fourier transform from x to k space to a gaussian f(x)~exp(-x^2), you get f(k)~exp(-k^2). However, doing discrete Fourier transform to set of values...

Hello all, first time here and I have really silly problem... I am working on something in MATLAB, in which I have to make discrete Fourier transform of gaussian distributed variable. i.e. array of numbers which are taken from f(x)~exp(-x^2). I know that when you Fourier transform it with...
