Args
`single_amplitudes`	`ndarray` [NxN] array storing single excitation amplitudes corresponding to t[i,j] * (a_i^\dagger a_j - H.C.)
`double_amplitudes`	`ndarray` [NxNxNxN] array storing double excitation amplitudes corresponding to t[i,j,k,l] * (a_i^\dagger a_j a_k^\dagger a_l - H.C.)

Args

single_amplitudes

ndarray
