Calculate excitations after iDMRG

Hi. I have been working with a Hubbard Diamond Chain model for some time now. I have done simulations both locally and in a cluster with simulations to find the ground State with iDMRG. I am now trying to calculate excited states but I am unable to do so. First, I put into context the simple calcula...
