Sokolsky, Pierre | Effect of clouds on apertures of space-based air fluorescence detectors | Space-based ultra-high-energy cosmic ray detectors observe fluorescence light from extensive air showers produced by these particles in the troposphere. Clouds can scatter and absorb this light and produce systematic errors in energy determination and spectrum normalization. We study the possibilit... | Fluorescence; Cloud detection; Extensive air showers | 2004-01 |

DeTar, Carleton | High-precision lattice QCD confronts experiment | The recently developed Symanzik-improved staggered-quark discretization allows unquenched lattice-QCD simulations with much smaller (and more realistic) quark masses than previously possible. To test this formalism, we compare experiment with a variety of nonperturbative calculations in QCD draw... | Staggered quarks | 2004-01 |

Vardeny, Zeev Valentine | Ultrafast spectroscopy of excitons in single-walled carbon nanotubes | We studied the femtosecond dynamics of photoexcitations in films containing semiconducting and metallic single-walled carbon nanotubes (SWNTs), using various pump-probe wavelengths and intensities.We found that confined excitons and charge carriers with subpicosecond dynamics dominate the ultrafas... | Ultrafast spectroscopy; Excitons; Single-walled carbon nanotubes; SWNT | 2004-01 |
