Static Response of the Strongly Coupled Electron Gas from Diffusion Monte Carlo
Muhammed H. Güneş, Yubo Yang, Vitaly Gorelov +4
The local field factor of the HEG describes how exchange and correlation modify the response to a static perturbation, and enters dielectric screening, effective electron--e…
Fingerprints of Excitonic Collective Modes in the Two-Dimensional Electron Gas
Jakob Wolff, Silvana Botti, Lucia Reining +1
The two-dimensional homogeneous electron gas (2D HEG) is a prototype system of fundamental interest that can be realized experimentally over a wide range of densities. Here, we inv…
Signature of Short-Range Order in Static Response of the Three-Dimensional Electron Gas
Muhammed H. Güneş, Yubo Yang, Vitaly Gorelov +4
The three-dimensional electron gas is a fundamental model in condensed matter physics and quantum chemistry, and the exchange-correlation energy derived from it serves as the start…
Designing explicit functionals for the charge density in terms of a potential
Muhammed H. Güneş, Ayoub Aouina, Vitaly Gorelov +2
One of the most powerful strategies to address properties of real many-body systems is to incorporate data obtained for models, for example, to use data of the homogeneous electron…
Electron charge dynamics and charge separation: A response theory approach
Lionel Lacombe, Lucia Reining, Vitaly Gorelov
This study applies response theory to investigate electron charge dynamics, with a particular focus on charge separation. We analytically assess the strengths and limitations of li…
