Nuclear PDFs NLO - status report review of the EPS09 results
2011/1/10
review the current status of the global DGLAP analysis of nuclear parton distribution functions, nPDFs.
Challenges for Modeling Nuclear Structure: Are the Proton and Neutron Masses and A-body Interactions Relevant?
Modeling Nuclear Structure A-body Interactions Relevant
2011/1/7
We discuss some of the challenges that future nuclear modeling may face in order to improve the description of the nuclear structure. One challenge is related to the need for A-body nuclear interactio...
Recent progress on nuclear potentials from lattice QCD
Recent progress nuclear potentials lattice QCD
2011/1/10
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...
Nuclear spin pumping and electron spin susceptibilities
Nuclear spin pumping electron spin susceptibilities
2010/11/23
In this work we present a straightforward formalism to evaluate the nuclear spin dynamics driven by hyperfine interaction with non-equilibrium electron spins. To describe the dynamics up to second ord...
The KamLAND-experiment and Soliton-like Nuclear Georeactor. Part 1. Comparison of Theory with Experiment
The KamLAND-experiment Soliton-like Nuclear Georeactor
2010/11/18
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 co...
Dark Atoms of the Universe: towards OHe nuclear physics
Dark Atoms Universe OHe nuclear physics
2011/1/10
The nonbaryonic dark matter of the Universe is assumed to consist of new stable particles. A specific case is possible, when new stable particles bear ordinary electric charge and bind in heavy ”atoms...
Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes
Effective Field Theory High-Precision Calculations of Nuclear Electroweak Processes
2011/1/7
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 r...
Critical-doping universality for cuprate superconductors: Oxygen nuclear-magnetic-resonance investigation of Ca(x)La(1-x)Ba(1.75-x)La(0.25+x)Cu(3)O(y)
cuprate superconductors Oxygen nuclear-magnetic-resonance investigation
2010/11/18
The critical doping levels in cuprates, where the ground state changes its nature (from an an-
tiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin ...
Coherent control of the cooperative branching ratio for nuclear x-ray pumping
Coherent control cooperative branching ratio nuclear x-ray pumping
2010/11/11
Coherent control of nuclear pumping in a three level system driven by x-ray light is investigated. In single nuclei, the pumping performance is determined by the branching ratio of the excited state p...
Coupled-channels density-matrix approach to low-energy nuclear collision dynamics: A technique for quantifying quantum decoherence effects on reaction observables
Coupled-channels density-matrix low-energy nuclear collision dynamics reaction observables
2010/11/11
The coupled-channels density-matrix technique for nuclear reaction dynamics, which is based on the Liouville-von Neumann equation with Lindblad dissipative terms, is developed with the inclusion of fu...
Interference and nuclear medium effects on the eta-mesic nuclear spectrum
Nuclear interaction of N⋆ (1535) Eta-mesic nucleus 25Mg
2011/1/6
he missing-mass spectrum obtained in a recoil-free transfer reaction p(27Al,3He)−p′X is
analyzed. We find that the observed peak structure arises from the coherent contributions from
two reac...
Adiabatic refocusing of nuclear spins in Tm3+:YAG
Adiabatic refocusing nuclear spins Tm3+:YAG
2010/10/20
We show that the optical absorbance detection of nuclear spin echo gives direct access to the spin concentration, unlike most coherent signal detection techniques where the signal intensity/amplitude ...
Nuclear Collective Excitation by a Short Strong Laser Pulse
Nuclear Collective Short Strong Laser Pulse
2010/10/27
We derive the conditions on the average laser energy and the mean photon number such that
a strong short laser pulse causes collective nuclear excitation. We use the nuclear Giant Dipole Resonance as...
Universal quantum control of two-electron spin quantum bits using dynamic nuclear polarization
Universal quantum control two-electron spin quantum bits dynamic nuclear polarization
2010/10/27
One fundamental requirement for quantum computation is to perform universal manipulations
of quantum bits at rates much faster than the qubit’s rate of decoherence. Recently,
fast gate operations ha...
