Note on exchange phenomena in the thomas atom
WebThe concept of exchange energy as it arises in Thomas‐Fermi theory is examined. It is found that the imposition of Hermitian symmetry upon the single particle Thomas‐Fermi density matrix changes the single particle exchange energy density operator in … WebAug 30, 2024 · Electron exchange is a purely quantum mechanical effect driven by the Pauli principle. The Slater determinant wavefunctions ensure the exchange term will only be non-zero for electrons of the same spin, with the resulting exchange energy manifesting as a negative correction to the Coulomb energy. The Hartree-Fock equations can then be written
