Hi everyone,
I've been reading about the Klein Gordon equation with the Coulomb Potential. The full solution can be found here:
http://wiki.physics.fsu.edu/wiki/in...#Klein-Gordon_equation_with_Coulomb_potential
I'm confused near the beginning of this. I understand that the solution is going to look like
$$\Phi(r,t) = R(r)Y(\theta,\phi)T(t)$$
since this is radially symmetric and a second order linear homogeneous partial differential equation, so it is separable. What I don't understand is why all the solutions I look at assume
$$T(t)=e^{-iEt/\hbar}.$$
I've looked up a number of solutions and they all make this assumption without explanation, so I'm assuming I'm missing something obvious. Can anyone explain it to me?
Thanks!
