Rogachev, Andrey | Influence of high magnetic fields on the superconducting transition of one-dimensional Nb and MoGe nanowires | The effects of a strong magnetic field on superconducting Nb and MoGe nanowires with diameter ~10 nm have been studied. We have found that the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory of thermally activated phase slips is applicable in a wide range of magnetic fields and describes well the ... | Nb; MoGe; Superconducting transition; Langer-Ambegaokar-McCumber-Halperin; LAMH; Phase slips | 2005-01 |

Vardeny, Zeev Valentine | Organic random lasers in the weak-scattering regime | We used the ensemble-averaged power Fourier transform (PFT) of random laser emission spectra over the illuminated area to study random lasers with coherent feedback in four different disordered organic gain media in the weak scattering regime, where the light mean free path, ℓ* is much larger tha... | Organic random lasers; Gain media; pi-conjugated polymers; Opal photonic crystal; RG6; Optical gain; Chicken breast | 2005-01 |

DeTar, Carleton | Semileptonic decays of D mesons in three-flavor lattice QCD | We present the first three-flavor lattice QCD calculations for D→ rrlv and D→ Klv semileptonic decays. Simulations are carried out using ensembles of unquenched gauge fields generated by the MILC Collaboration. With an improved staggered action for light quarks, we are able to simulate at light ... | Semileptonic decay; Staggered quarks | 2005-01 |
