Exchange-Correlation Hole in Polarized Insulators: Implications for the Microscopic Functional Theory of Dielectrics
Gerardo Ortiz, Ivo Souza, Richard M. Martin
We present a simple and direct proof that the exchange-correlation hole, and therefore the exchange-correlation energy, in a polarized insulator is not determined by the bulk densi…

Mott Transition in Degenerate Hubbard Models: Application to Doped Fullerenes
Olle Gunnarsson, Erik Koch, Richard M. Martin
The Mott-Hubbard transition is studied for a Hubbard model with orbital degeneracy N, using a diffusion Monte-Carlo method. Based on general arguments, we conjecture that the Mott-…
