New insights into the laser produced electron–positron pairs
New Journal of Physics, 2013 We report new results from the intense laser target interaction experiment that produces relativistic electron–positron pairs. Laser to electron energy transfer, inferred using x-ray and neutron measurements, was found to be consistent with the measured ...

The extremely high-energy electron experiment (XEP) onboard the Arase (ERG) satellite
Earth, Planets and Space, 2018 The extremely high-energy electron experiment (XEP) onboard the Arase (ERG) satellite is designed to measure high-energy electrons in the Earth’s radiation belts. The XEP was developed by taking advantage of our technical heritage of high-energy particle

Advanced Physics Research, EarlyView.A pure inverse spin Hall effect (ISHE) is demonstrated in ferromagnetic Ni₈₀Fe2₀/YIG heterostructures via the longitudinal spin Seebeck effect. By employing symmetry‐controlled geometries and reference samples, anomalous Nernst contributions are quantitatively eliminated, revealing intrinsic spin–charge conversion in Ni₈₀Fe2₀.

Electron acceleration in relativistic GRB shocks [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007 The shock model of gamma-ray bursts (GRBs) has two free parameters: ϵ B and ϵ e . It has been shown that ϵ B should range between few×10 −

Advanced Physics Research, EarlyView.The top panel shows the electronic band structure, which illustrates how the electronic energy varies with momentum along different high‐symmetry directions within the first Brillouin zone. Band structure determines the electronic character of a crystalline solid.

The Principal Role of Chorus Ducting for Night‐Side Relativistic Electron Precipitation
Geophysical Research LettersNight‐side chorus waves are often observed during plasma sheet injections, typically confined around the equator and thus potentially responsible for precipitation of ≲100 keV electrons.

The Generation of Ultraintense Half-Cycle Attosecond X-ray Pulse
Ultrafast ScienceFor applications of attosecond pulse (AP), the intensity and isolation of AP are all important pursuits. We proposed a double-foil target regime to generate an ultraintense and isolated half-cycle attosecond x-ray pulse (AXP) that exhibits unipolar ...

Relativistic electronic dressing
, 2002 We study the effects of the relativistic electronic dressing in laser-assisted electron-hydrogen atom elastic collisions. We begin by considering the case when no radiation is present. This is necessary in order to check the consistency of our calculations and we then carry out the calculations using the relativistic Dirac-Volkov states.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
Astronomische Nachrichten, EarlyView.ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.
