Dear Physics Forum, I have a question about quantum mechanics. I know that the solutions of a Hamiltonian will form a complete basis. However, for a case of a finite well, in the region of bound states (E<0), the number of eigenfunctions is finite, I wonder that they are enough to form a...

Hi Physics Forum, I am a student, doing something about electromagnetic pulses. I want to ask a question: If we find the effects of EM pulses on some systems, is it convenient to use Fourier transformation to make these pulses look like sinusoidal? Or we can use other kinds of...
