Hi
I am interested in doing the finite temperature study for Fermi Hubbard model. Is it straightforward to write the infinite temperature state using the already present subroutines, if I change the local Hilbert space to four dimension (\up, \down, \empty, \up\down.) And then writing the infinite temperature state as a bell entangled pair out of this four D Hilbert space. Can you suggest something how should I proceed with this.
Also, the general way of proceeding in Fermionic system with particular electron filling, we start with an initial state with that filling and we conserve particle number N and I guess this works.
But how do one start with infinite temperature state with particular filling and evolve that state to finite temperature. Please advise.
Thanks
Aman
