{ "abstract": "<p>The theoretical understanding of plasmon behavior is crucial for an accurate interpretation of inelastic<br>\nscattering diagnostics in many experiments. We highlight the utility of linear-response time-dependent density<br>\nfunctional theory (LR-TDDFT) as a first-principles framework for consistently modeling plasmon properties.<br>\nWe provide a comprehensive analysis of plasmons in aluminum from ambient to warm dense matter conditions<br>\nand assess typical properties such as the dynamical structure factor, the plasmon dispersion, and the plasmon<br>\nlifetime. We compare our results with scattering measurements and with other TDDFT results as well as models<br>\nsuch as the random phase approximation, the Mermin approach, and the dielectric function obtained using static<br>\nlocal field corrections of the uniform electron gas parametrized from path-integral Monte Carlo simulations. We<br>\nconclude that results for the plasmon dispersion and lifetime are inconsistent between experiment and theories<br>\nand that the common practice of extracting and studying plasmon dispersion relations is an insufficient procedure<br>\nto capture the complicated physics contained in the dynamic structure factor in its full breadth.<br>\n </p>", "type": "dataset", "version": "1", "author": [ { "family": "Ramakrishna, Kushal" }, { "family": "Cangi, Attila" }, { "family": "Dornheim, Tobias" }, { "family": "Vorberger, Jan" }, { "family": "Baczewski, Andrew" } ], "publisher": "Rodare", "DOI": "10.14278/rodare.663", "id": "663", "issued": { "date-parts": [ [ 2021, 3, 8 ] ] }, "title": "Data for: \"First-principles modeling of plasmons in aluminum under ambient and extreme conditions\"" }
