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
