Jet conversions in a quark-gluon plasma
(American Physical Society, 2007)Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic q((q) over bar )g -> gq((q) over bar )and the inelastic ... -
K+ Total Cross-Sections on C-12 and Medium Effects in Nuclei
(American Physical Society, 1992)The total cross sections for K+ mesons on carbon and deuterium nuclei have been measured at eleven momenta in the range 450-740 MeV/c. The experimental technique was of the standard transmission type. The K+ meson is the ... -
Medium modifications of the rho meson in nuclear photoproduction
(American Physical Society, 2010)We extend our recent study of dilepton invariant-mass spectra from the decays of rho mesons produced by photon reactions off nuclei. We specifically focus on experimental spectra as recently measured by the CLAS Collaboration ... -
New astrophysical S factor for the (15)N(p,gamma)(16)O reaction via the asymptotic normalization coefficient (ANC) method
(American Physical Society, 2008)The (15)N(p,gamma)(16)O reaction provides a path from the CN cycle to the CNO bi-cycle and CNO tri-cycle. The measured astrophysical factor for this reaction is dominated by resonant capture through two strong J(pi) = 1(-) ... -
Nonlinear magneto-optical rotation of elliptically polarized light RID A-1272-2007 RID B-9041-2008
(American Physical Society, 2003)We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically polarized light propagating in a medium with atomic coherence. We show that this effect ... -
np elastic spin transfer measurements at 788 MeV
(American Physical Society, 1991)We have measured the spin-transfer parameters K(LL), K(SL), K(LS), and K(SS) at 788 MeV from 47-degrees to 177-degrees c.m., and also uncovered a 10-16 % normalization discrepancy which affects all previous np elastic spin ... -
Numerical procedure for analyzing impurity-induced resonant-state STM images observed in high-T-c superconductors
(American Physical Society, 2004)Numerical procedure is developed for analyzing impurity-induced resonant-state STM images observed in high-T-c superconductors, and is applied to three sets of higher resolution data provided to us by J. C. Seamus Davis ... -
Plasmon mass and Drude weight in strongly spin-orbit-coupled two-dimensional electron gases
(American Physical Society, 2011)Spin-orbit-coupled two-dimensional electron gases (2DEGs) are a textbook example of helical Fermi liquids, i.e., quantum liquids in which spin (or pseudospin) and momentum degrees of freedom at the Fermi surface have a ... -
Proton-Lambda correlations in central Au+Au collisions at root s(NN)=200 GeV
(American Physical Society, 2006)We report on p-Lambda, p-(Lambda) over bar, (p) over bar-Lambda, and (p) over bar-(Lambda) over bar correlation functions constructed in central Au-Au collisions at root s(NN) = 200 GeV by the STAR experiment at RHIC. The ... -
Quasiparticle resonant states induced by a unitary impurity in a d-wave superconductor
(American Physical Society, 2000)The quasiparticle resonant states around a single nonmagnetic impurity with unitary scattering in a d-wave superconductor is studied by solving the Bogoliubov-de Gennes equations based on a t-J model. Both the spatial ... -
Reduced effect of impurities on the universal pairing scale in the cuprates
(American Physical Society, 2010)We consider the effect of nonmagnetic impurities on the onset temperature T* for the d-wave pairing in spin-fluctuation scenario for the cuprates. We analyze intermediate coupling regime when the magnetic correlation length ... -

Specific-heat discontinuity in impure two-band superconductors
(American Physical Society, 2003)The Ginzburg-Landau coefficients and the jump of the specific heat are calculated for a disordered two-band superconductor. We start with the analysis of a more general case with arbitrary anisotropy. While the specific-heat ... -
Tests of transfer reaction determinations of astrophysical S factors
(American Physical Society, 1999)The O-16(He-3,d)F-17 reaction has been used to determine asymptotic normalization coefficients for transitions to the ground and first excited states of F-17. Th, coefficients provide the normalization for the tails of the ... -
Theory of femtosecond coherent anti-Stokes Raman backscattering enhanced by quantum coherence for standoff detection of bacterial spores
(American Physical Society, 2005)Backscattered signal of coherent anti-Stokes Raman spectroscopy can be an extremely useful tool for remote identification of airborne particles, provided the signal is sufficiently large. We formulate a semiclassical theory ... -
Three-body decay of (6)Be
(American Physical Society, 2009)Three-body correlations for the ground-state decay of the lightest two-proton emitter (6)Be are studied both theoretically and experimentally. Theoretical studies are performed in a three-body hyperspherical-harmonics ... -
What can we Learn from a 2nd Phi-Meson Peak in Ultrarelativistic Nuclear Collisions
(American Physical Society, 1994)The decay width of a phi meson is reduced from its vacuum value as its mass decreases in hot hadronic matter as a result of the partial restoration of chiral symmetry. This reduction is, however, cancelled by collisional ...
