Give the Hartree-Fock state of jellium.

grid Grid

The discretization to use.

n_electrons int

Number of electrons in the system.

spinless bool

Whether to use the spinless model or not.

plane_wave bool

Whether to return the Hartree-Fock state in the plane wave (True) or dual basis (False).

The jellium model is built up by filling the lowest-energy single-particle states in the plane-wave Hamiltonian until n_electrons states are filled.
