Time evolution of a wave packet from the time-independent Schroedinger equation [duplicate]
Starting off with the time-independent Schroedinger equation (TISE)
$\quad \quad
-\frac{\hbar^2}{2m} \nabla^2 \psi + V(r, \theta) \psi = E\, \psi,$
I would like to study the time evolution of an ...

Only final result from NDSolve
Finally, I started to play with differential equations in Mathematica.
And I have faced the problem, which seems to me so basic that I'm afraid this question is going to be closed soon. However, I'...

Schrödinger eigenvalue problem in two dimensions (Harmonic Oscillator)
I read here the discussion about how to solve a one-dimensional eigenvalue problem. I am wondering, how can one generalize these methods to two dimensions?
For example, how to solve this equation:
$$...

NDSolve for complex pde
My goal is to use NDSolve to solve the complex pde $F(z,t)$ with complex derivative $\partial_{z}=\frac{1}{2}(\partial_{x}-i \partial_{y}).$ The equation can be ...
