Short time dynamics with initial correlations
TL;DR: Exact cancellation of the two integrals is found if the initial state is thermal equilibrium, which is an important consistency criterion, and results are given for the time evolution of the correlation energy.

Abstract: The short-time dynamics of correlated systems is strongly influenced by initial correlations, giving rise to an additional collision integral in the non-Markovian kinetic equation. Exact cancellation of the two integrals is found if the initial state is thermal equilibrium, which is an important consistency criterion. Analytical results are given for the time evolution of the correlation energy, which are confirmed by comparisons with molecular dynamics simulations.

Ultracold neutral plasmas
TL;DR: In this article, it was shown that strongly coupled plasmas, in which the electrical interaction energy between charged particles exceeds the average kinetic energy, reverse the traditional energy hierarchy underlying basic plasma concepts such as Debye screening and hydrodynamics.

Ultracold neutral plasmas
TL;DR: In this article, the average kinetic energy during equilibration and extremely fast recombination in ultracold neutral plasmas is studied. But the results are limited to the case where the average energy is proportional to the number of particles in the system.

TL;DR: By varying the electron temperature, it is shown that electron screening modifies the equilibrium ion temperature and damped oscillations of the ion kinetic energy that are a unique feature of equilibration of a strongly coupled plasma.

TL;DR: In this paper, the authors used simple assumptions about the underlying temperature distribution and ion motion to derive the Doppler-broadened absorption spectrum, which is related to the average temperature in the plasma.
Relation between full NEGF, non-Markovian and Markovian transport equations
TL;DR: In this article, the authors provide an overview and critical review of the use of causal Ansatzes with the accent on derivation of (quantum) transport equations from the standard Kadanoff-Baym (KB) equations for the non-equilibrium Green's functions (NEGF).

TL;DR: In this paper, the generalized Kadanoff-Baym (KB) ansatz is replaced by a modification which is called the generalized KB ansatz, which is fully consistent with the dynamical structure of the theory and is independent of any specific representation.
