Hello all, I got 2 questions for the Kondo lattice in the ALPS. The Hamiltonian in the models.xml for Kondo lattice reads -t*fermion_hop(i,j) + J*exchange(i,j) 1. Does the code only work at half-filling? 2. The second term in the Hamiltonian does not look like the original one, namely, the original Hamiltonian of the Kondo model contains a term \sum_{i} s_i \cdot S_i, here the s (S) are the spin of the conducting (local) electrons. I wonder what's going on. Thank you very much for your attention. Sincerely, Fu-Jiun
