I believe the problem is that FQE assumes that each `FermionOperator` is in the spin-orbital basis. So indices 0, 1, 2, ... refer to (spatial orbital 0, alpha), (spatial orbital...
Yes, if you create a wavefunction with only alpha fermions (I think you do this in the original post) then it can be used as a representation of spinless fermions
We could potentially add some more sophisticated logic to try to guess the most efficient representation of the operator when it is passed as a `FermionOperator`. Currently it will only...
