Thermal stitching: Extending the reach of quantum fermion solvers

Justin Clifford Smith, Kieron Burke

For quantum fermion problems, many accurate solvers are limited by the temperature regime in which they can be usefully applied. The Mermin theorem implies the uniqueness of an eff…

Warming Up Density Functional Theory

Justin C. Smith, Francisca Sagredo, Kieron Burke

Density functional theory (DFT) has become the most popular approach to electronic structure across disciplines, especially in material and chemical sciences. Last year, at least 3…

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…
