This is a quantum mechanics problem, but the problem itself is reduced (naturally) to a differential equations problem.
I have to solve the following equation:
[tex]\frac{\partial}{\partial t}\psi (x,t) = i\sigma \psi (x,t)[/tex]
where [itex]\sigma > 0[/itex]
The initial condition is:
[tex]\psi (x,0) = \sqrt{\frac{2}{L_0}}\sin \left(\frac{n\pi x}{L_0}\right)[/tex]
and the boundary conditions are:
[tex]\psi (0,t) = \psi(L(t),t) = 0[/tex]
where [itex]L(t)[/itex] is a smooth function with [itex]L(0)=L_0[/itex].
I don't even know how to begin
. Any ideas?
