Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

This might belong in the quantum mechanics section, so I apologize if I placed this thread in the wrong place.

My question is: how do I calculate the gradient of a multiparticle wavefunction? For example, suppose that a wavefunction [tex]\psi[/tex] describing the probability amplitude for two particles with coordinates [tex](r_1,\phi_1)[/tex] and [tex](r_2,\phi_2)[/tex]:

[tex]

\psi = r_1r_2e^{i(\phi_1+\phi_2)}

[/tex]

and I want to find the gradient of [tex]\psi[/tex]. Is this even possible? What about the curl?

Thanks!
