openfermion.transforms.inverse_fourier_transform
Apply inverse Fourier transform to change hamiltonian in plane wave dual basis.
openfermion.transforms.inverse_fourier_transform(
hamiltonian, grid, spinless
)
\[
a^\dagger_v = \sqrt{1/N} \sum_m {c^\dagger_m \exp(i k_v r_m)}
a_v = \sqrt{1/N} \sum_m {c_m \exp(-i k_v r_m)}
\]
