A Novel Coprecipitation Path to a High‐Performing Ni/MgO Catalyst for Carbon Dioxide Methanation

open access: yesChemSusChem, EarlyView.
A highly active Ni/MgO CO2 methanation catalyst is derived from a novel crystalline bimetallic single‐source precursor. This material is characterized by its high specific surface area and interdispersed nanoparticles originating from a solid solution. The novel crystalline bimetallic single‐source precursor (Ni1–xMgx)12(CO3)8(OH)6O · y H2O with x = 0 ...

On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

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.
