Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?

Albert Einstein; Boris Podolsky; N. Rosen · Physical Review · 1935

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the ...

Self-interaction correction to density-functional approximations for many-electron systems

John P. Perdew; Alex Zunger · Physical review. B, Condensed matter · 1981

The exact density functional for the ground-state energy is strictly self-interaction-free (i.e., orbitals demonstrably do not self-interact), but many approximations to it, including the local-spin-density (LSD) approxi...
