NR/HEP: roadmap for the future [PDF]

, 2012
Physic in curved spacetime describes a multitude of phenomena, ranging from astrophysics to high-energy physics (HEP). The last few years have witnessed further progress on several fronts, including the accurate numerical evolution of the gravitational ...

Progress and prospects in high energy astrophysics.

Proceedings of the National Academy of Sciences of the United States of America, 1975
The traditional kind of astrophysicist is, in a sense, an "ap-plied" physicist, who computes models for stars and galaxies based on relatively well-understood properties of atoms and nuclei, Newtonian gravity, and other branches of classical physics. But

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.

Laboratory laser acceleration and high energy astrophysics: (gamma)-ray bursts and cosmic rays

, 1998
Recent experimental progress in laser acceleration of charged particles (electrons) and its associated processes has shown that intense electromagnetic pulses can promptly accelerate charged particles to high energies and that their energy spectrum is ...

Optimization of Thermally Radiative and Mass Wavy Flow Analysis Affected by Induced Magnetic Field and Joule Heating

Energy Science &Engineering, EarlyView.
ABSTRACT The role of magnetic induction is declared fundamental in many technological systems, including electric generators, inductors, transformers, and so on. This is an important source for converting energy from one form to another while utilizing electromagnetic induction. This phenomenon is efficient when the induced magnetic field is introduced

End of a Dark Age?

, 2016
We argue that dark matter and dark energy phenomena associated with galactic rotation curves, X-ray cluster mass profiles, and type Ia supernova data can be accounted for via small corrections to idealized general relativistic spacetime geometries due to

Extrapolation Boundary Conditions for 2‐D Smoothed Particle Hydrodynamics

International Journal for Numerical Methods in Fluids, EarlyView.
This paper introduces novel inflow, outflow, and wall boundaries for the WCSPH method. Utilising innovative concepts from finite volume methods, fluid properties of sequential dynamic particles with varying distances to boundaries are extrapolated to ghost and wall particles using first‐order Taylor series expansion.

Nuclear Theory and Science of the Facility for Rare Isotope Beams

, 2014
The Facility for Rare Isotope Beams (FRIB) will be a world-leading laboratory for the study of nuclear structure, reactions and astrophysics. Experiments with intense beams of rare isotopes produced at FRIB will guide us toward a comprehensive ...

Linear Discontinuity Sharpening for Highly Resolved and Robust Magnetohydrodynamics Simulations

International Journal for Numerical Methods in Fluids, EarlyView.
This study applies a reconstruction scheme, “hybrid MUSCL–THINC” for finite volume methods developed by Chiu et al., to magnetohydrodynamics (MHD) simulations. Furthermore, the robustness is improved by a modification that deactivates an artificial compression by THINC depending on the non‐linearity of MHD discontinuities.
