to lists.

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.)

Returns
single_amplitudes_list(list): list of lists with each sublist storing a list of indices followed by single excitation amplitudes i.e. [[[i,j],t_ij], ...] double_amplitudes_list(list): list of lists with each sublist storing a list of indices followed by double excitation amplitudes i.e. [[[i,j,k,l],t_ijkl], ...]
