Exact conditions on the temperature dependence of density functionals
Kieron Burke, Justin C. Smith, Paul E. Grabowski +1
Universal exact conditions guided the construction of most ground-state density functional approximations in use today. We derive the relation between the entropy and Mermin free e…
Exact thermal density functional theory for a model system: Correlation components and accuracy of the zero-temperature exchange-correlation approximation
Justin C Smith, Aurora Pribram-Jones, Kieron Burke
Thermal density functional theory calculations often use the Mermin-Kohn-Sham scheme, but employ ground-state approximations to the exchange-correlation (XC) free energy. In the si…
The Hubbard Dimer: A density functional case study of a many-body problem
Diego Carrascal, Jaime Ferrer, Justin C. Smith +1
This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model. The relation…
