Hi, I have been trying to use imaginary time propagation to get the ground state and excited states eigen function but the results I got is different from the analytical solution. I know that to get excited states, I should propagate 2 or more orthogonal functions depending on the number of excited states that you want. I just would like to check whether there is any requirement on the initial guess that you use to propagate. If I choose a random set of numbers to propagate, will it always contain my ground state?(adsbygoogle = window.adsbygoogle || []).push({});
