Electron Density Structure Measurements With Scattered Intense Laser Beam

Contributions to Plasma Physics, EarlyView.
ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.

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.

Numerical Modeling of Isochoric Heating Experiments Using the Troll Code in the Warm Dense Matter Regime

Contributions to Plasma Physics, EarlyView.
ABSTRACT Experiments of isochoric heating by protons of solid material were recently performed at LULI laser facilities. In these experiments, protons, produced from target normal sheath acceleration (TNSA) of Au foil with the PICO2000 laser, deposit their energy into an aluminum or copper foil initially at room temperature and solid density.

Coherence, Transport, and Chaos in 1D Bose–Hubbard Model: Disorder vs. Stark Potential

Fortschritte der Physik, EarlyView.
Quantum coherence and criticality in finite Bose–Hubbard chains are investigated using exact diagonalization. Thermal fluctuations, Stark potential, and disorder reshape coherence, visibility, and superfluid response. Finite‐size systems show signatures of quantum criticality, with disorder suppressing global superfluidity but preserving local ...

Exposing and Challenging “Grit” in Physics Education

Science Education, EarlyView.
ABSTRACT In STEM education, grit is increasingly the focus of research, with scholars and educators seeking to develop and test interventions that will enhance persistence. As part of the special issue Centering Affect and Emotion Toward Justice and Dignity in Science Education, in this paper, we use interviews with 12 white physics faculty to show ...

Broken Structural Symmetry in Terahertz Detectors: Physical Mechanisms, Device Design, and Recent Advances

Small Structures, EarlyView.
Breaking the structural symmetry of devices is a crucial design strategy that endows terahertz (THz) detectors with novel operating mechanisms and unique characteristics. This study provides an in‐depth discussion on symmetry‐breaking‐induced phenomena, novel asymmetric structures, and dominant detection mechanisms.

Study of shock waves and related phenomena motivated by astrophysics

, 2016
This paper discusses the recent research in High-Energy-Density Physics at our Center. Our work in complex hydrodynamics is now focused on mode coupling in the Richtmyer- Meshkov process and on the supersonic Kelvin-Helmholtz instability. These processes

Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown

High Voltage, EarlyView.
ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.

Alternative Approaches for Estimating Highest‐Density Regions

International Statistical Review, EarlyView.
Summary Among the variety of statistical intervals, highest‐density regions (HDRs) stand out for their ability to effectively summarise a distribution or sample, unveiling its distinctive and salient features. An HDR represents the minimum size set that satisfies a certain probability coverage, and current methods for their computation require ...
