Searches for Electric Dipole Moments—Overview of Status and New Experimental Efforts

open access: yesUniverse, 2019
Searches for permanent electric dipole moments (EDMs) of fundamental particles, atoms and molecules are promising experiments to constrain and potentially reveal beyond Standard Model (SM) physics.

SARS-CoV-2 Inactivation Simulation Using 14 MeV Neutron Irradiation

open access: yesLife, 2021
The SARS-CoV-2 virus is deadly, contagious, can cause COVID-19 disease, and endangers public health and safety. The development of SARS-CoV-2 inactivation technology is crucial and imminent in current pandemic period. Neutron radiation is usually used to

Neutron lifetime puzzle and neutron–mirror neutron oscillation [PDF]

open access: yesThe European Physical Journal C, 2019
The discrepancy between the neutron lifetimes measured in the beam and trap experiments can be explained via the neutron $n$ conversion into mirror neutron $n'$, its dark partner from parallel mirror sector, provided that $n$ and $n'$ have a tiny mass splitting order $10^{-7}$ eV.

Observation of Ground-State Two-Neutron Decay [PDF]

open access: yes, 2012
Neutron decay spectroscopy has become a successful tool to explore nuclear properties of nuclei with the largest neutron-to-proton ratios. Resonances in nuclei located beyond the neutron dripline are accessible by kinematic reconstruction of the decay ...

CUBIC NEUTRONS [PDF]

open access: yesModern Physics Letters A, 2012
The neutron is largely spherical and incompressible in atomic nuclei. These two properties are however challenged in the extreme pressure environment of a neutron star. Our variational computation within the Cornell model of Coulomb gauge QCD shows that the neutron (and also the Δ3/2 baryon) can adopt cubic symmetry at an energy cost of about 150 MeV.

Sparse-View Neutron CT Reconstruction Using a Modified Weighted Total Difference Minimization Method

open access: yesApplied Sciences, 2021
Indirect neutron imaging is an effective method for nondestructive testing of spent nuclear fuel elements. Considering the difficulty of obtaining experimental data in a high-radiation environment and the characteristic of high noise of neutron images ...

Binary Neutron Stars with Arbitrary Spins in Numerical Relativity [PDF]

open access: yes, 2015
We present a code to construct initial data for binary neutron star systems in which the stars are rotating. Our code, based on a formalism developed by Tichy, allows for arbitrary rotation axes of the neutron stars and is able to achieve rotation rates ...

Evolution of Spin Period and Magnetic Field of the Crab Pulsar: Decay of the Braking Index by the Particle Wind Flow Torque

open access: yesUniverse, 2022
The evolutions of a neutron star’s rotation and magnetic field (B-field) have remained unsolved puzzles for over half a century. We ascribe the rotational braking torques of pulsar to both components, the standard magnetic dipole radiation (MDR) and ...

Neutron skins and neutron stars [PDF]

open access: yesAIP Conference Proceedings, 2013
The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb.

Phonons and Thermal Expansion Behavior of NiSi and NiGe

open access: yesFrontiers in Chemistry, 2018
We have carried out first principles calculations of the vibrational and thermodynamic behavior in NiSi and isostructural compound NiGe. Phonon density of states has also been measured in NiSi using inelastic neutron scattering techniques.
