The entanglement of a system serves a key measure of its quantum properties that can be used to quantify its utility in quantum information processors. Nonetheless, entanglement is a notoriously challenging and expensive quantity to compute for many-body systems. In this work, we demonstrate how a new recursive formalism can be used to compute the finite temperature properties of quantum...
The KS-DFT is the standard method to model the electronic structure due to its accuracy and computational efficiency. The reduction in computation cost compared to other ab initio methods is due to a formally exact mapping onto an effective single-electron problem. DFT calculations of a various material properties require as input the so-called exchange—correlation (XC) kernel. Yet, little is...
Adiabatic connection approaches have long been used in ground-state density functional theory for analyzing exact and approximate density functional theory, and it has more recently been applied to both thermal and ensemble versions of the theory. In this talk, I'll introduce the adiabatic connection and what changes for this tool when at the high temperatures and densities common to warm...
