NEWPORT NEWS, VA, October 16, 2014 – Like dancers swirling on the dance floor with bystanders looking on, protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, ...
Upper limits on the observational effects of nuclear pasta in neutron stars
relativity – gravitational waves – dense matter – stars neutron – stars
2011/7/21
The effects of the existence of exotic nuclear shapes at the bottom of the neutron star inner crust - nuclear `pasta' - on observational phenomena are estimated by comparing the limiting cases that th...
Oscillations of hot, young neutron stars: Gravitational wave frequencies and damping times
Oscillations of hot young neutron stars
2011/7/21
We study how the frequencies and damping times of oscillations of a newly born, hot proto-neutron star depend on the physical quantities which characterize the star quasi-stationary evolution which fo...
Relativistic separable interaction kernel of the neutron-proton system with inelasticities
neutron-proton system Relativistic separable interaction
2011/7/20
Within a covariant Bethe-Salpeter approach, the relativistic complex separable neutron-proton interaction kernel is proposed. The uncoupled partial-wave states with the total angular momentum $J$=0,1 ...
Testing the density matrix expansion against ab initio calculations of trapped neutron drops
density matrix neutron drops
2011/7/20
Microscopic input to a universal nuclear energy density functional can be provided through the density matrix expansion (DME), which has recently been revived and improved.
Constraining the neutron-neutron scattering length with \eftnopi
neutron-neutron scattering length
2011/7/20
We compute a model-independent correlation between the difference of neutron-neutron and proton-proton scattering lengths |a(nn)-a^C(pp)| and the splitting in binding energies between Helium-3 and tri...

Periodic Box FHNC calculations neutron star crustal matter
2011/7/20
Neutron star crustal matter, whose properties are relevant in many models aimed at explaining observed astrophysical phenomena, has so far always been studied using a mean field approach. In order to ...

Fast Neutron Detection 6Li-loaded Liquid Scintillator
2011/7/21
We report on the development of a fast neutron detector using a liquid scintillator doped with enriched Li-6. The lithium was introduced in the form of an aqueous LiCl micro-emulsion with a di-isoprop...

2010/11/23
We report inelastic neutron scattering measurements of the magnetic excitations in SrFe2As2,
the parent of a family of iron-based superconductors. The data extend throughout the Brillouin
zone and u...

Lorentz CPT violation of the bound Neutron Free Precession 3He/129Xe co-magnetometer
2010/12/20
We report on the search for Lorentz violating sidereal variations of the frequency difference of colocated spin-species while the Earth and hence the laboratory reference frame rotates with respect to...
