Temperature and the strong-interaction limit of density functional theory

The strictly correlated electron approach to density functional theory, first proposed by Seidl and coworkers [1-4], offers a unique perspective on finite-temperature density functional theory and one of its application areas, simulations in the warm dense matter regime. Recent work relating tied coordinate-temperature-interaction scaling to the strong-interaction limit of density functional theory is presented via formal and numerical results. Strategies for analyzing the competition between strong interaction and temperature in complicated physical systems will be discussed.
