#48 interacting fermionic-hubbard model

[MRINAL KANTI GIRI]

Hi Daniel,

I want to study dynamics of the interacting Fermi-Hubbard model of two fermions and want check <n(t)>.
1. 1st i am trying to check static interacting fermi-hubbard hamiltonian to check wether it works or not...But its not working...Can you please help me why its not working??(1st attached file)
2. Second problem is that the dynamics of the interacting fermi-hubbard hamiltonian which is also not working. Here Two fermions are traped at the center sites (i,i+1) and intial psi states are also given which is elove in time.</n(t)>

Thank you in advance.
