What was discovered

The energy of a system of electrons is determined by its electron density, reducing the many-body problem to single-electron equations (Kohn-Sham). It is the most widely used quantum chemistry method for molecules and solids.

Nobel Prize in Chemistry 1998 (Kohn and Pople).

What it led to

  • Routine computational chemistry
  • In silico design of catalysts and materials
  • Computational materials science

Built on

  • Thomas-Fermi model
  • Hartree-Fock method

Made possible

  • quantum chemistry programs (Gaussian, VASP)
  • materials databases (Materials Project)
