Use the Second Order Hamiltonian node to include additional second order Hamiltonian terms. This and the following three domain conditions (First Order Hamiltonian, Left, First Order Hamiltonian, Right, and Zeroth Order Hamiltonian) are primarily for the case of multicomponent wave function.

In the Hamiltonian input table, use the lists to enter the Hamiltonian row index (m), Hamiltonian column index (n), Left differential operator (i), and Right differential operator (j). Use the input fields to enter the A parameter (dimensionless) and the Description.
