Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes
Effective Field Theory High-Precision Calculations Nuclear Electroweak Processes
2010/12/29
High-precision calculations of electroweak processes in light nuclei are of great importance for multiple reasons. Gerry Brown together with Dan-Olof Riska published in 1972 a famous calculation on ra...
Recent progress on nuclear potentials from lattice QCD
Recent progress on nuclear potentials lattice QCD
2011/1/7
A new method for nuclear potentials is reviewed. The strategy to extract the potential from the Nambu-Bethe-Salpeter wave function in lattice QCD is explained and the first result based on the method ...
Curvature effect on nuclear pasta: Is it helpful for gyroid appearance?
Curvature effect nuclear pasta gyroid appearance
2011/1/6
In supernova cores and neutron star crusts, nuclei are thought to deform to rod-like and slablike shapes, which are often called “nuclear pasta.” We study the equilibrium properties of the nuclear pas...
We present measurements of both $p_t$-integral and $p_t$-differential azimuth quadrupole components of two-particle correlations on azimuth ($\phi$) and pseudorapidity ($\eta$) for unidentified hadron...
Coherent state transfer between an electron- and nuclear spin in 15N@C60
Coherent state transfer electron- and nuclear spin
2010/11/25
Electron spin qubits in molecular systems o er high reproducibility and the ability to self assemble into larger architectures. However, interactions between neighbouring qubits are `always-on' and al...
Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects
Nuclear spins magnetic moments quadrupole moments Cu isotopes probes core polarization effects
2010/12/31
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using t...
Closed-Form Solutions to A Category of Nuclear Norm Minimization Problems
Closed-Form Solutions Nuclear Norm Minimization Problems
2010/11/24
It is an efficient and effective strategy to utilize the nuclear norm approximation to learn low-rank matrices, which arise frequently in machine learning and computer vision. So the exploration of n...
Nuclear coherent population transfer with x-ray laser pulses
Nuclear coherent population transfer x-ray laser pulses
2010/12/27
Coherent population transfer in a nuclear three-level system via stimulated Raman adiabatic passage is studied. To compensate for the lack of $\gamma$-ray laser sources, we envisage accelerated nucle...
Nuclear absorption effects on Lambda-bar/p-bar ratio in heavy ion collisions
Nuclear absorption Lambda-bar/p-bar ratio heavy ion collisions
2010/12/27
An enhanced \lp\ ratio in heavy-ion relative to $p+p$ collisions has been proposed as one of the signatures for the Quark-Gluon Plasma (QGP) formation. A significantly large \Lp\ ratio of 3.5 has bee...

The KamLAND-experiment and Soliton-like Nuclear Georeactor. Part 1. Comparison of Theory with Experiment
The KamLAND-experiment Soliton-like Nuclear Georeactor. Part 1. Comparison Theory Experiment
2010/12/29
We give an alternative description of the data produced in the KamLAND experiment, assuming the existence of a natural nuclear reactor on the boundary of the liquid and solid phases of the Earth's cor...
The orientation of the nuclear obscurer of the AGNs
galaxies statistics — galaxies Seyfert — galaxies nuclei — galaxies spiral
2010/11/15
We examine the distribution of axis ratios of a large sample of disk galaxies hosting type 2 AGNs selected from the Sloan Digital Sky Survey and compare it with a well-defined control sample of non-ac...
Constraints on the threshold K- nuclear potential from FINUDA (stopped K-, pi-) hypernuclear spectra
Constraints threshold K- nuclear potential FINUDA (stopped K-, pi-) hypernuclear spectra
2010/12/29
1s(Lambda) hypernuclear formation rates in stopped K- reactions on several p-shell targets are derived from hypernuclear formation spectra measured recently by the FINUDA Collaboration and are compare...
