Active-Space N-Representability Constraints for Variational Two-Particle Reduced Density Matrix Calculations
(2010)The ground-state energy of a system of fermions can be calculated by minimizing a linear functional of the two-particle reduced density matrix (2-RDM) if an accurate set of N-representability conditions is applied. In this ... -
Beyond the Death of Linear Response: 1/f Optimal Information Transport
(2010)Nonergodic renewal processes have recently been shown by several authors to be insensitive to periodic perturbations, thereby apparently sanctioning the death of linear response, a building block of nonequilibrium statistical ... -
Determination of the Axial-Vector Weak Coupling Constant with Ultracold Neutrons
(2010)A precise measurement of the neutron decay beta asymmetry A(0) has been carried out using polarized ultracold neutrons from the pulsed spallation ultracold neutron source at the Los Alamos Neutron Science Center. Combining ... -
Detrended fluctuation analysis of scaling crossover effects
(2010)Detrended fluctuation analysis (DFA) is one of the most frequently used fractal time series algorithms. DFA has also become the tool of choice for analysis of the short-time fluctuations despite the fact that its validity ... -
Polarization Transfer in the He-4((e)over-right-arrow, e '(p)over-right-arrow)H-3 Reaction at Q(2)=0.8 and 1.3 (GeV/c)(2)
(2010)Proton recoil polarization was measured in the quasielastic He-4((e) over right arrow, e '(p) over right arrow)H-3 reaction at Q(2) = 0.8 and 1.3 (GeV/c)(2) with unprecedented precision. The polarization-transfer coefficients ... -
Scaling of the F-2 Structure Function in Nuclei and Quark Distributions at x > 1
(2010)We present new data on electron scattering from a range of nuclei taken in Hall C at Jefferson Lab. For heavy nuclei, we observe a rapid falloff in the cross section for x > 1, which is sensitive to short-range contributions ... -
