Use the Zeroth Order Hamiltonian node to include additional zeroth order Hamiltonian terms. Also see the comment about the built-in factor in
Second Order Hamiltonian (
Equation 5-1).
In the Hamiltonian input table, use the drop down menus to enter the
Hamiltonian row index (m) and
Hamiltonian column index (n). Use the input fields to enter the
Zeroth order Hamiltonian parameter (Unit:
1/m^2) and the
Description.
