RealQM, the essence — H, H₂, He running in parallel

Same CPU solver, same box=8 / soft=1 mesh. One atom, the molecule, and the two-electron atom — the same four-line method, only the kernels and V_KK differ.

RealQM, the essence — H, H₂, He running in parallel

H — one atom → −0.5

H₂ — the bond (R=1.44) → ≈ −1.2

He — two electrons, one +2 kernel → ≈ −2.9
