Lead Hamiltonians:
<pre>
H_lead = np.array([[ 0. , -1. ,  0.2,  0. ],
                   [-1. ,  0. , -1. ,  0.2],
                   [ 0.2, -1. ,  0. , -1. ],
                   [ 0. ,  0.2, -1. ,  0. ]])

Scattering Hamiltonian:

                   [ 0 ,0.2 ,   0,-0.8,  0, 0. ],
                   [ 0 ,  0 ,-0.8,   0,0.2, 0. ],
