We present a quantum theory for the dynamic structure factors in nonequilibrium, correlated, two-component systems such as plasmas or warm dense matter. The polarization function, which is needed as the input for the calculation of the structure factors, is calculated in nonequilibrium based on a perturbation expansion in the interaction strength. To make our theory applicable for x-ray scattering, a generalized Chihara decomposition for the total electron structure factor in nonequilibrium is…

Ab initio Path Integral Monte Carlo Results for the Dynamic Structure Factor of Correlated Electrons: From the Electron Liquid to Warm Dense Matter.

This work presents the first ab initio results for S(q,ω) by carrying out extensive path integral Monte Carlo simulations and developing a new method for the required analytic continuation, which is based on the stochastic sampling of the dynamic local field correction G( q,ω).

Thomson scattering from dense inhomogeneous plasmas.

In this work, implications for Thomson scattering spectra for inhomogeneous plasmas in the warm dense matter regime based on a gradient expansion within real-time Green's-functions theory are discussed.

Electronic Density Response of Warm Dense Matter

Matter at extreme temperatures and pressures — commonly known as warm dense matter (WDM) in the literature — is ubiquitous throughout our Universe and occurs in a number of astrophysical objects such

Ab initio simulation of warm dense matter

Warm dense matter (WDM) -- an exotic state of highly compressed matter -- has attracted high interest in recent years in astrophysics and for dense laboratory systems. At the same time, this state is

A signature of non-local plasma fluctuations in Thomson scattering

Thomson scattering from plasma fluctuations in a plasma layer with an electron density maximum is considered. It is shown that the scattering spectrum shape is highly dependent on whether the



Dynamical local-field factors and effective interactions in the three-dimensional electron liquid.

An analytical study of the dynamical local-field factors associated with the response of a homogeneous two-dimensional interacting electron liquid as functions of momentum, frequency, and density and shows that both the quantitative and qualitative behaviors of the interaction are sensitive to the inclusion of dynamical correlations.

Ab initiosimulations of the dynamic ion structure factor of warm dense lithium

We present molecular dynamics simulations based on finite-temperature density functional theory that determine self-consistently the dynamic ion structure factor and the electronic form factor in

Long-wavelength limit of the dynamical local-field factor and dynamical conductivity of a two-component plasma

A systematic approach to the optical conductivity is given within a dielectric function formalism and the existence of the third moment sum rule can be shown analytically.

Ab initio approach to model x-ray diffraction in warm dense matter.

It is demonstrated how the static electron-electron structure factor in warm dense matter can be obtained from density functional theory in combination with quantum Monte Carlo data. In contrast to

Influence of local-field corrections on Thomson scattering in collision-dominated two-component plasmas.

The dynamic structure factor, which determines the Thomson scattering spectrum, is calculated via an extended Mermin approach and strong deviations of the plasmon resonance position due to the electron-electron correlations are observed at increasing Brueckner parameters r(s).

Energy relaxation in dense, strongly coupled two-temperature plasmas.

A quantum kinetic approach for the energy relaxation in strongly coupled plasmas with different electron and ion temperatures is presented and a balance equation for the energies of electrons and ions connecting kinetic, correlation, and exchange energies with a quite general expression for the electron-ion energy-transfer rate is derived.

X-ray Thomson Scattering in Warm Dense Matter without the Chihara Decomposition.

This work provides unambiguous first principles calculations of the dynamic structure factor of warm dense beryllium, independent of the Chihara form, by treating bound and free states under a single formalism and compares results from TDDFT to Chihara-based calculations for experimentally relevant conditions in shock-compressed berylla.

Ab initio calculation of the ion feature in x-ray Thomson scattering.

An ab initio method is applied for the calculation of the form factor of bound electrons, the slope of the screening cloud of free electrons, and the ion-ion structure factor in warm dense beryllium to facilitate a better understanding of x-ray scattering inwarm dense matter and an accurate measurement of ion temperatures which would allow determining nonequilibrium conditions.
