We investigate the emergence of electronic excitations from the inhomogeneous electronic structure at warm dense matter parameters based on first-principles calculations. The emerging modes are controlled by the imposed perturbation amplitude. They include satellite signals around the standard plasmon feature, transformation of plasmons to optical modes, and double-plasmon modes. These modes exhibit a pronounced dependence on the temperature. This makes them potentially invaluable for the diagnostics of plasma parameters in the warm dense matter regime. We demonstrate that these modes can be probed with present experimental techniques.

“…Dense quantum plasmas are presently of high relevance in many fields, including the astrophysics of planets and compact stars, for example, References [1, 2] as well as laboratory experiments with high‐intensity lasers or free electron lasers. The most striking application is the quest for inertial confinement fusion.…”

Günter Kelbg did remarkable early work in the field of quantum statistical physics, in particular for dense quantum plasmas. In 2022 we celebrated his 100th birthday. On this occasion, we give a brief overview of his main scientific achievements in the field of quantum plasmas, complemented by some biographical background of his research and teaching environment at Rostock University. Kelbg's main achievement is the derivation of a regularized quantum pair potential. We demonstrate that it is still of high relevance for molecular dynamics and quantum Monte Carlo simulations of dense plasmas.

Представлена математическая модель термомеханического воздействия проникающего излучения на изделие микроэлектроники. Модель основана на уравнениях термоупругости, которые являются следствием квантовых кинетических уравнений для фононов. Перенос тепла описан законом сохранения энергии и уравнением Каттанео, которое учитывает конечность скорости распространение тепла. Колебания решетки рассмотрены в приближении линейной теории упругости. В целом модель определяет распределение температуры, потока энергии, деформации и напряжения. Разработаны разностные схемы для решения уравнений модели. Эффективность разработанной модели проверена путем решения задачи о термоударе.
