Exact density functional obtained via the Levy constrained search

Paula Mori-Sánchez, Aron J. Cohen

A stochastic minimization method for a real-space wavefunction, , constrained to a chosen density, , is developed. It enabl…

Qualitative breakdown of the unrestricted Hartree-Fock energy

Paula Mori-Sánchez, Aron J. Cohen

The stretching of closed-shell molecules is a qualitative problem for restricted Hartree-Fock that is usually circumvented by the use of unrestricted Hartree-Fock (UHF). UHF is wel…

The derivative discontinuity of the exchange-correlation functional

Paula Mori-Sánchez, Aron J. Cohen

The derivative discontinuity is a key concept in electronic structure theory in general and density functional theory in particular. The electronic energy of a quantum system exhib…

Dramatic changes in electronic structure revealed by fractionally charged nuclei

Aron J. Cohen, Paula Mori-Sánchez

Discontinuous changes in the electronic structure upon infinitesimal changes to the Hamiltonian are demonstrated. Remarkably, these are revealed in one and two electron molecular s…

Extension of many-electron theory and approximate density functionals to fractional charges and fractional spins

Weitao Yang, Paula Mori-Sanchez, Aron J. Cohen

The exact conditions for density functionals and density matrix functionals in terms of fractional charges and fractional spins are known, and their violation in commonly used func…
