Mishchenko, Eugene | Effect of electron-electron interactions on the conductivity of clean graphene | Minimal conductivity of a single undoped graphene layer is known to be of the order of the conductance quantum, independent of the electron velocity. We show that this universality does not survive electron-electron interaction, which results in nontrivial frequency dependence. We begin with analyzi... | Optical conductivity; Perturbation theory | 2007-05 |

Zhdanov, Michael S. | Integral electric current method in 3-D electromagnetic modeling for large conductivity contrast | Abstract-We introduce a new approach to 3-D electromagnetic (EM) modeling for models with large conductivity contrast. It is based on the equations for integral current within the cells of the discretization grid, instead of the electric field or electric current themselves, which are used in the c... | Electromagnetic modeling; Integral electric current method; 3-D modeling; High conductivity contrast; Integral equations | 2007-05 |

Gerton, Jordan | Nanoscale fluorescence imaging using a single-wall carbon nanotube | A single-wall carbon nanotube attached to an AFM probe is used for near-field optical imaging of 20 nm diameter fluorescent spheres and 5 nm diameter CdSe quantum dots. | 2007-05 | |

Gerton, Jordan | Optimizing contrast of tip-enhanced fluorescence microscopy for imaging high-density samples | Quantum dots are imaged using tip-enhanced fluorescence microscopy. Optimization of the operation parameters leads to high-contrast images of high-density samples and a novel photon analysis improves contrast further. | 2007-05 | |

DeTar, Carleton | QCD equation of state with 2+1 flavors of improved staggered quarks | We report results for the interaction measure, pressure, and energy density for nonzero-temperature QCD with 2 + 1 flavors of improved staggered quarks. In our simulations, we use a Symanzik improved gauge action and the Asqtad O(a2) improved staggered quark action for lattices with temporal extent ... | Staggered quarks; Quark-gluon plasma | 2007-05 |

Boehme, Christoph | Room temperature electrical detection of spin coherence in C60 | An experimental demonstration of electrical detection of coherent spin motion of weakly coupled, localized electron spins in thin fullerene C60 films at room temperature is presented. Pulsed electrically detected magnetic resonance experiments on vertical photocurrents through Al/C60/ZnO samples sh... | Spin coherence | 2007-05 |
