Equation of state at finite baryon density based on lattice QCD
lattice QCD baryon density Equation of state
2011/7/21
We employ the lattice QCD data on Taylor expansion coefficients to extend our previous parametrization of the equation of state to finite baryon density.
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.
Three-dimensional calculation of inhomogeneous structure in low-density nuclear matter
low-density nuclear matter inhomogeneous structure
2011/7/20
In low-density nuclear matter which is relevant to the crust region of neutron stars and collapsing stage of supernovae, non-uniform structures called "nuclear pasta" are expected.
Charged-particle multiplicity density at mid-rapidity in central Pb-Pb collisions at sqrt(sNN) = 2.76 TeV
Charged-particle multiplicity density mid-rapidity central Pb-Pb collisions sqrt(sNN) 2.76 TeV
2010/12/29
The first measurement of the charged-particle multiplicity density at mid-rapidity in Pb-Pb collisions at a centre-of-mass energy per nucleon pair sqrt(sNN) = 2.76 TeV is presented. For an event sampl...
Density-dependent nucleon-nucleon interaction from three-nucleon forces
Density-dependent nucleon-nucleon interaction three-nucleon forces
2011/1/6
Microscopic calculations based on realistic nuclear hamiltonians, while yielding accurate results for the energies of the ground and low-lying excited states of nuclei with A ≤ 12, fail to reproduce t...
Spin-Density Wave near the Vortex Cores of Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$
Spin-Density Wave Vortex Cores
2010/11/18
Competition with magnetism is at the heart of high temperature superconductivity, most intensely felt near a vortex core. To investigate vortex magnetism we have developed a spatially resolved probe u...
Density-dependent nuclear interactions and the beta decay of 14C: chiral three-nucleon forces and Brown-Rho scaling
Effective field theory at finite density chiral three-nucleon force Brown-Rho scaling
2011/1/7
We study the role of density-dependent low-momentum nucleon-nucleon interactions in describing the anomalously long beta decay lifetime of 14C. We approach this problem both from the perspective of ch...

Influence of the Solar and Density Perturbations on the Neutrino Parameters
the Solar and Density Perturbations the Neutrino Parameters
2010/10/27
There are reasons to believe that the solar matter density fluctuates around an equilibrium profile. One of these reasons is a resonance between the Alfv´en waves and the g-modes inside the Sun ...
