Multi‐million‐year evolution of the Greenland Ice Sheet in Inglefield Land, North Greenland
Journal of Quaternary Science, EarlyView.ABSTRACT Information on past sensitivity of the Greenland Ice Sheet to climate change is of importance for optimizing models simulating the future evolution of ice mass loss. While the ice‐sheet change during the Lateglacial and Holocene is relatively well constrained, the long‐term (multi‐million‐year) evolution of the Greenland Ice Sheet remains ...

Fixing Two-Nucleon Weak-Axial Coupling L_{1,A} From mu-d Capture
, 2006 We calculate the muon capture rate on the deuteron to next-to-next-to-leading order in the pionless effective field theory. The result can be used to constrain the two-nucleon isovector axial coupling L_{1,A} to +/- 2 fm^3 if the muon capture rate is ...

Electroweak structure of light nuclei within chiral effective field theory [PDF]
, 2013 We review the results of the most recent calculations for the electromagnetic structure of light nuclei, the weak muon capture on deuteron and 3He and the weak proton-proton capture reaction at energies of astrophysical interest, performed within the ...

Nucleon axial structure from lattice QCD
Journal of High Energy Physics, 2020 We present a new analysis method that allows one to understand and model excited state contributions in observables that are dominated by a pion pole. We apply this method to extract axial and (induced) pseudoscalar nucleon isovector form factors, which ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning
Advanced Quantum Technologies, EarlyView.The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Shallow Nitrogen Vacancy Color Centers in Diamond by Ion Implantation
Advanced Quantum Technologies, EarlyView.This study investigates the formation of shallow nitrogen‐vacancy (NV) centers in CVD diamond through broad‐beam ion implantation across a SiO₂ layer. By adjusting the ion incidence angle, the distribution of NV centers is controlled, as predicted by sytopping and range of ions in matter (SRIM) simulations and confirmed by angle‐resolved X‐ray ...

Weak reactions on 12C within the Continuum Random Phase Approximation with partial occupancies [PDF]
, 1999 We extend our previous studies of the neutrino-induced reactions on 12C and muon capture to include partial occupation of nuclear subshells in the framework of the continuum random phase approximation. We find, in contrast to the work by Auerbach et al.,

High Ionic Conduction in Rb‐ and Cs‐Mixed Cation Amide for Energy Storage
Small, EarlyView.A mixed cation‐amide solid solution, Rb0.5Cs0.5NH2, based on the interaction between RbNH2‐ and CsNH2, has been developed. The Rb⁺/Cs⁺ cationic substitution leads to structural stabilization, resulting in high ionic conductivity in the Rb0.5Cs0.5NH2 compared to the single compounds.

Optimized capture section for a muon accelerator front end
Physical Review Special Topics. Accelerators and Beams, 2014 In a muon accelerator complex, a target is bombarded by a multi-MW proton beam to produce pions, which decay into the muons which are thereafter bunched, cooled, and accelerated.
