v-Representability on a one-dimensional torus at elevated temperatures
Sarina M. Sutter, Markus Penz, Michael Ruggenthaler +2
We extend a previous result [Sutter et al., J. Phys. A: Math. Theor. 57, 475202 (2024)] to give an explicit form of the set of -representable densities on the one-dimensional to…
Constrained Search in Imaginary Time
Markus Penz, Robert van Leeuwen
We introduce an imaginary-time evolution method to evaluate the pure-state constrained-search functional from density-functional theory formulated on finite lattices. Simultaneousl…
Dynamically screened vertex correction to
Y. Pavlyukh, G. Stefanucci, R. van Leeuwen
Diagrammatic perturbation theory is a powerful tool for the investigation of interacting many-body systems, the self-energy operator encoding all the variety of scattering proc…
Approximate energy functionals for one-body reduced density matrix functional theory from many-body perturbation theory
Klaas J. H. Giesbertz, Anna-Maija Uimonen, Robert van Leeuwen
We develop a systematic approach to construct energy functionals of the one-particle reduced density matrix (1RDM) for equilibrium systems at finite temperature. The starting point…
