Laser‐Driven Charge‐Transfer Dynamics in the Quaterthiophene–Fullerene Donor/Acceptor Interface

open access: yesChemPhotoChem, EarlyView.
This ab initio study investigates laser‐induced charge‐transfer in a quaterthiophene/fullerene complex at varying intensities of the external pulse. Pulses above 3 GW cm−2 are needed to trigger charge transfer, which is enabled by vibrations in the donor. Under stronger field intensities, transient effects in the system prevail.

Dynamic Properties of the Warm Dense Uniform Electron Gas With the qSTLS Dielectric Scheme

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The recently derived Fourier–Matsubara expansion of imaginary–time correlation functions comprises an exact result of linear response theory for finite‐temperature quantum many‐body systems. In its density–density version, the expansion facilitates systematic comparisons between quasi‐exact ab initio path integral Monte Carlo simulations and ...

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.
