EFFECTIVE FIELD THEORY IN NUCLEAR PHYSICS
Electromagnetic hadron physics nuclear physics
<
2014/12/22
The Electromagnetic and Hadronic Physics sub-community of nuclear physics held a town hall meeting at Jefferson Lab during November 30 to December 4 of 2000. This is is our combined contribution to th...
This is the report of the NSAC Subcommittee on Nuclear Theory in response to a charge by the funding agencies to review and evaluate current NSF and DOE supported efforts in nuclear theory and identif...
Nuclear parity violation in effective field theory
Photovoltaic (pv) nuclear nuclear parameterized coupling
<
2014/12/20
We reformulate the analysis of nuclear parity violation (PV) within the framework of effective field theory (EFT). To O(Q), the PV nucleon–nucleon (NN) interaction depends on five a priori unknown con...
Sigma exchange in the nuclear force and effective field theory
The meson particle spectrum nuclear force
<
2014/12/20
In the phenomenological description of the nuclear interaction an important role is traditionally played by the exchange of a scalar I=0 meson, the sigma, of mass 500–600 MeV, which however is not see...
Nuclear central force in the chiral limit
Chiral perturbation theory function quality component physical spectrum energy function
<
2014/12/20
Chiral perturbation theory supplemented by the Omnes function is employed to study the strength of the isoscalar central nuclear interaction, GS, in the chiral limit vs the physical case. A very large...
Constraints on the variability of quark masses from nuclear binding
Nuclear binding the light quark heavy nuclei attractive
<
2014/12/19
Based on recent work on nuclear binding, we update and extend the anthropic constraints on the light quark masses, with results that are more tightly constrained than previously obtained. We find that...
Detection of spin injection into a double quantum dot: Violation of magnetic-field-inversion symmetry of nuclear polarization instabilities
Detection of spin injection double quantum dot: Violation nuclear polarization instabilities
<
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...
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...
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...
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...
Control of the direction and rate of nuclear spin flips in InAs quantum dots using detuned optical pulse trains
nuclear spin flips InAs quantum dots detuned optical pulse trains
<
2010/4/8
We find that detuning an optical pulse train from electronic transitions in quantum dots controls the direction of nuclear spin flips. The optical pulse train generates electron spins that precess abo...

2010/4/8
Sharp threshold-like transitions between two stable nuclear spin polarizations are observed in optically pumped individual InGaAs self-assembled quantum dots embedded in a Schottky diode when the bias...

2010/4/8
Nuclear spin polarization dynamics are measured in optically pumped individual GaAs/AlGaAs interface quantum dots by detecting the time-dependence of the Overhauser shift in photoluminescence (PL) spe...
Coherence and control of quantum registers based on electronic spin in a nuclear spin bath
Coherence quantum registers electronic spin nuclear spin bath

2010/4/7
We consider a protocol for the control of few-qubit registers comprising one electronic spin embedded in a nuclear spin bath. We show how to isolate a few proximal nuclear spins from the rest of the e...
