Vardeny, Zeev Valentine; Gellermann, Werner | Raman scattering gain in DOO-PPV films | We have investigated the optical emission characteristics of poly(2,5-dioctyloxy-p-phenylenevinylene) (DOO-PPV) thin films under high intensity ps pulsed laser excitation (Ipump > 1 MW/ cm2). We observed that the emission spectrum consist of a spectrally narrowed emission (SNE) band (FWHM ~ 10 nm)... | DOO-PPV; Raman scattering gain; Stimulated emission; Strongly coupled vibrations | 1997 |

Mishchenko, Eugene | Full counting statistics of a charge pump in the Coulomb blockade regime | We study full charge counting statistics (FCCS) of a charge pump based on a nearly open single electron transistor. The problem is mapped onto an exactly soluble problem of a nonequilibrium g=1/2 Luttinger liquid with an impurity. We obtain an analytic expression for the generating function of the... | Counting statistics; Luttinger liquid | 2001-11 |

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 |

Wu, Yong-Shi | Perturbative formulation and nonadiabatic corrections in adiabatic quantum-computing schemes | Adiabatic limit is the presumption of the adiabatic geometric quantum computation and of the adiabatic quantum algorithm. But in reality, the variation speed of the Hamiltonian is finite. Here we develop a general formulation of adiabatic quantum computing, which accurately describes the evolution... | Perturbative formulation; Nonadiabatic corrections; Adiabatic | 2004-02 |

Gondolo, Paolo | Daily modulation due to channeling in direct dark matter crystalline detectors | The channeling of the ion recoiling after a collision with a weakly interacting massive particle (WIMP) in direct dark matter crystalline detectors produces a larger scintillation or ionization signal than otherwise expected. Channeling is a directional effect, which depends on the velocity distrib... | | 2011 |

Gondolo, Paolo | Directional recoil rates for WIMP direct detection | New techniques for the laboratory direct detection of dark matter weakly interacting massive particles (WIMPs) are sensitive to the recoil direction of the struck nuclei.We compute and compare the directional recoil rates dR/d cosθ, (where θ is the angle measured from a reference direction in th... | WIMP; Weakly interacting massive particles; WMAP 3; Directional recoil; Halo models | 2008-02 |

Gondolo, Paolo | XENON10/100 dark matter constraints in comparison with CoGeNT and DAMA: Examining the L eff dependence | We consider the compatibility of DAMA/LIBRA, CoGeNT, XENON10 and XENON100 results for spin-independent (SI) dark matter weakly interacting massive particles, particularly at low masses (~10 GeV), assuming a standard dark matter halo. The XENON bounds depend on the scintillation efficiency factor Lef... | | 2011 |

Gondolo, Paolo | Detectability of weakly interacting massive particles in the Sagittarius dwarf tidal stream | Tidal streams of the Sagittarius dwarf spheroidal galaxy (Sgr) may be showering dark matter onto the solar system and contributing ~(0:3-23)% of the local density of our galactic halo. If the Sagittarius galaxy contains dark matter in the form of weakly interacting massive particles (WIMPs), the ext... | WIMP; Weakly interacting massive particles; Sagittarius dwarf galaxy; Recoil energy; Sgr stream | 2005-02 |
