AP19679049 — Thermodynamic and radiation properties of dense degenerate plasma

Objective of the project:

The goal of this project is to study the thermodynamic and radiation properties of dense degenerate plasma. The main objective of the project is to study the behavior of plasma at high densities and temperatures, when quantum effects become significant and electrons become degenerate.

Relevance of the project:

The relevance of the project to study the thermodynamic and radiative properties of dense degenerate plasma is due to a number of fundamental and applied factors: Dense degenerate plasma is a key state inside stars, especially in objects such as white dwarfs and neutron stars. Studying its properties helps to understand the processes occurring in these objects, such as thermonuclear reactions, thermal equilibrium and the evolution of stars. Degenerate electron plasmas also play an important role in the context of nuclear fusion, both under natural conditions in stars and under controlled conditions on Earth. Studying its properties may lead to the development of more effective methods for controlling thermonuclear reactions and the creation of more efficient energy sources. Experiments and simulations of dense degenerate plasma can be carried out both in laboratory conditions and using computational methods. This opens the way to new discoveries and technological breakthroughs in the field of plasma physics. Taking into account all these factors, the study of the thermodynamic and radiation properties of dense degenerate plasma remains a relevant and important area of scientific research.

Results obtained: Within the research project, theoretical and numerical studies of dense degenerate plasma properties relevant to inertial confinement fusion and astrophysical environments were conducted. Binding energies, static dipole polarizabilities, and thermodynamic properties were calculated using effective potentials and variational methods. The effects of quantum nonlocality and correlation on informational measures such as Shannon entropy and Fisher information were analyzed. Spectral line shifts of hydrogen-like ions and collision process coefficients were evaluated over a wide range of densities and temperatures. Thermodynamic properties and plasma heating rates under external fields were also investigated. The obtained results were compared with literature and experimental data and showed good agreement.
