Short Wavelength Limit of the Dynamic Matsubara Local Field Correction

Contributions 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{

Instantaneous Normal Modes of Yukawa Liquids

Contributions to Plasma Physics, EarlyView.
ABSTRACT The instantaneous normal mode (INM) approach, which extends the normal mode description of collective excitations in solids to liquids, is applied to strongly coupled, three‐dimensional Yukawa liquids. Based on data from Langevin dynamics simulations, we compute the instantaneous normal modes across a wide range of coupling and screening ...

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

Contributions 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 ...

Predicting the Uniform Electron Gas Stopping Power at Moderate and Strong Coupling

Contributions to Plasma Physics, EarlyView.
ABSTRACT This paper presents a detailed study of the stopping power of a homogeneous electron gas in moderate and strong coupling regimes using the self‐consistent version of the method of moments as the key theoretical approach capable of expressing the dynamic characteristics of the system in terms of the static ones, which are the moments.

Creep properties and constitutive model of diabase in deep water conveyance tunnels

Deep Underground Science and Engineering, EarlyView.
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.

Multiphysics modeling of coupling compressed‐air energy storage‐thermal storage in salt caverns: An approach to insoluble sediment as heat reservoir feasibility analysis

Deep Underground Science and Engineering, EarlyView.
This study investigates the feasibility of utilizing insoluble sediments in salt caverns for short‐ and long‐term thermal energy storage applications. The analysis revealed three key thermal characteristics of these sediments: (1) thermal shock resistance, (2) temperature differential compensation capability during air injection, and (3) high ...

Influence of Sidewall Effects on Ejected Flame During Facade Calibration Tests: Experimental Analysis and Findings

Fire and Materials, EarlyView.
ABSTRACT The inclusion of sidewalls is a typical architectural feature in building façades, which has raised significant concerns about their potential to accelerate flame spread, particularly with the increasing prevalence of high‐rise buildings. This paper presents an experimental investigation and analysis of façade flame with a single sidewall ...
