Title: Light plasmon mode in the CFL phase

Abstract

The self-energies and the spectral densities of longitudinal and transverse gluons at zero temperature in the color-flavor-locked (CFL) phase are calculated. There appears a collective excitation, a light plasmon, at energies smaller than two times the gap parameter and momenta smaller than about eight times the gap. The minimum in the dispersion relation of this mode at some nonzero value of momentum corresponds to the van Hove singularity.

  • The field coupling in highly packed plasmonic nanoparticle arrays is not localized due to the energy transport via the sub-radiant plasmon modes, which is formed in addition to the regular super-radiant plasmon mode. Unlike the sub-radiant mode, the plasmon field of the super-radiant mode cannot extend over long distances since it decays radiatively with a shorter lifetime. The coupling of the plasmon fields of gold nanocubes (AuNCs) when organized into highly packed 2D arrays was examined experimentally. Multiple plasmon resonance optical peaks are observed for the AuNC arrays and are compared to those calculated using the discrete dipole approximation. Themore » calculated electromagnetic plasmon fields of the arrays displayed high field intensity for the nanocubes located in the center of the arrays for the lower energy super-radiant mode, while the higher energy sub-radiant plasmon mode displayed high field intensity at the edges of the arrays. The Raman signal enhancement by the super-radiant plasmon mode was found to be one hundred fold greater than that by sub-radiant plasmon mode because the super-radiant mode has higher scattering and stronger plasmon field intensity relative to the sub-radiant mode.« less
  • We report on first-order quasi-phase-matched frequency doubling of picosecond pulses to the green, using a sample of periodically poled lithium niobate. In cw mode-locked operation, 330 mW of average green power was generated with an average conversion efficiency of {approximately}52{percent}. With a quasi-cw mode-locked pulse train an average conversion efficiency of {approximately}65{percent} was achieved, and 1.3 W of green power (average power within the 10-{mu}s pulse envelope) was produced. At these powers there was no significant photorefractive damage, as confirmed by measured M{sup 2} beam-quality factors of {approximately}1.1 for both output fundamental and second-harmonic beams. {copyright} {ital 1996 Optical Societymore » of America.}« less
  • This article described results of phase II of a technology innovation competition for reflector compact fluorescent bulbs (R-CFLs) sponsored by DOE's Emerging Technologies program. DOE developed the competition to speed introduction of advanced, screw-based R-CFLs to the marketplace. The lamps are used in recessed can ceiling fixtures, the most popular fixture in American homes today. There have been concerns about heat buildup affecting the performance and longevity of R-CFLs in recessed fixtures located in insulated ceilings with airtight housings. To pass the competition, each lamp had to maintain acceptable light output levels and reach an average rated life of atmore » least 6,000 hours in high-temperature testing. The winning R-CFLs also had to meet rigorous specifications for light output, beam angle, and maximum operating temperature. Eight lamps, manufactured by GE, Osram Sylvania, and Philips, passed the requirements, joining other models by Philips and Feit that were identified as winners during Phase I of the competition. All of the winning lamps are Energy Star certified. The winning models will be promoted on DOE's R-CFLwebsite http://www.pnl.gov/rlamps.« less
  • The bulk viscosities of two color-superconducting phases, the color-flavor locked (CFL) phase and the 2SC phase, are computed and compared to the result for unpaired quark matter. In the case of the CFL phase, processes involving kaons and the superfluid mode give the largest contribution to the bulk viscosity since all fermionic modes are gapped. In the case of the 2SC phase, ungapped fermionic modes are present and the process u+d{r_reversible}u+s provides the dominant contribution. In both cases, the bulk viscosity can become larger than that of the unpaired phase for sufficiently large temperatures (T > or approx. 1 MeVmore » for CFL, T > or approx. 0.1 MeV for 2SC). Bulk viscosity (as well as shear viscosity) is important for the damping of r-modes in compact stars and thus can potentially be used as an indirect signal for the presence or absence of color-superconducting quark matter.« less
