Gondolo, Paolo | Annual modulation of dark matter in the presence of streams | In addition to a smooth component of weakly interacting massive particle (WIMP) dark matter in galaxies, there may be streams of material; the effects of WIMP streams on direct detection experiments is examined in this paper. The contribution to the count rate due to the stream cuts off at some char... | WIMP streams; Weakly interacting massive particles; Cutoff energy; Halo models; Sagittarius dwarf galaxy; Recoil energy; Sgr stream | 2006-08 |

Liu, Feng | Influence of quantum size effects on Pb island growth and diffusion barrier oscillations | Quantum size effects are successfully exploited in manipulating the growth of (111) oriented Pb islands on Si(111) substrate with a scanning tunneling microscope. The growth dynamics and morphology displayed can be well controlled through the quantum size effects defined by the island thicknesses ... | Quantum size effects; QSE; Pb island; Diffusion barrier oscillations | 2006-08 |

Wu, Yong-Shi | Numerical study of the three-dimensional random-field Ising model at zero and positive temperature | In this paper the three-dimensional random-field Ising model is studied at both zero temperature and positive temperature. Critical exponents are extracted at zero temperature by finite size scaling analysis of large discontinuities in the bond energy. The heat capacity exponent α is found to be n... | Bond energies; Ground states | 2006-08 |

Mishchenko, Eugene | Optical conductivity of a two-dimensional electron liquid with spin-orbit interaction | The interplay of electron-electron interactions and spin-orbit coupling leads to a new contribution to the homogeneous optical conductivity of the electron liquid. The latter is known to be insensitive to many-body effects for a conventional electron system with parabolic dispersion. The parabolic... | Optical conductivity; Electron liquid; Spin-orbit coupling | 2006-08 |

Harrison, Reid R.;Normann, Richard A. | Preliminary study of thermal impact of a microelectrode array implanted in the brain | One requirement of a chronically implantable, wireless neural interface device is the integration of electronic circuitry with the microelectrode array. Since the electronic IC dissipates a certain amount of power, it will affect the temperature in the tissues surrounding the implant site. In this ... | Microelectrode arrays; Neural recording; Utah Electrode Array; Thermal impact | 2006-08 |

Wu, Yong-Shi | Topological quantization of the spin Hall effect in two-dimensional paramagnetic semiconductors | We propose models of two-dimensional paramagnetic semiconductors where the intrinsic spin Hall effect is exactly quantized in integer units of a topological charge. The model describes a topological insulator in the bulk and a "holographic metal" at the edge, where the number of extended edge stat... | Topological insulator; Holographic metal; Edge states | 2006-08 |
