Is it possible to write down a statement about the asymptotic behaviour of the wave function after a small perturbation has been switched on?
So I have and initial wave function [itex]\psi_0[/itex] and the Hamiltonian
[tex]H=\begin{cases}
H_0 & t<0\\
H_0+V+R & t\geq 0
\end{cases}[/tex]
where V is a small perturbation and R and even smaller random extra perturbation. It would be nice to have the wavefunction [itex]\psi(t=\infty)[/itex] in terms of the eigenstates of V.
