Dear all,
I wonder if I can ask you how to setup a script to run an exact diagonalization of a spinless extended Hubbard model on a 4-sites system. I have read the tutorial but still do not get the idea of how to do it.
I want to specify the model Hamiltonian with a nearest neighbor hopping t, a nearest neighbor interaction strength V1 and a second nearest neighbor interaction strength V2. Where should I define these parameters?
thanks a lot for your kind help!
Best regards, Jun
