Apply inverse Fourier transform to change hamiltonian in
openfermion.transforms.inverse_fourier_transform(
hamiltonian, grid, spinless
)
plane wave dual basis.
\[ a^\dagger_v = \sqrt{1/N} \sum_m {c^\dagger_m \exp(i k_v r_m)} a_v = \sqrt{1/N} \sum_m {c_m \exp(-i k_v r_m)} \]
Args | |
|---|---|
| hamiltonian (FermionOperator): The hamiltonian in plane wave dual basis. grid (Grid): The discretization to use. spinless (bool): Whether to use the spinless model or not. |
