Thermodynamic-limit independence conjecture. The final results—the energy per unit cell and the ground-state density of the crystal—should not depend on the chosen thermodynamic-li…

In the reduced Hartree–Fock model for a perturbed crystal, let $\rho_{\nu,\varepsilon_{\rm F}}$ denote the induced electronic density associated with a defect density $\nu$, and le…
