    11 Feb 2016 | Online Presentations | Contributor(s): Debasish Dutta

    Opening remarks celebrating the Birck Nanotechnology Center 10th Anniversary.

  6. Engineering Diamond Color Centers for Quantum Information and Sensing

    11 Feb 2016 | Online Presentations | Contributor(s): Philip Hemmer

    For over a decade diamond color centers like the nitrogen-vacancy (NV) have been investigated for applications ranging from quantum storage registers to room temperature quantum computers to quantum enhanced bio-sensors. Recently silicon-vacancy (SiV) centers in diamond have showed potential to...

  7. Memory-Efficient Particle Annihilation Algorithm for Wigner Monte Carlo Simulations

    10 Feb 2016 | Online Presentations | Contributor(s): Paul Ellinghaus

    IWCE 2015 presentation. The Wigner Monte Carlo solver, using the signed-particle method, is based on the generation and annihilation of numerical particles. The memory demands of the annihilation algorithm can become exorbitant, if a high spatial resolution is used, because the entire...

  8. Ultra-Thin Silicon Membranes and Nanowires as Nanophononic and Thermoelectric Devices

    10 Feb 2016 | Online Presentations | Contributor(s): Davide Donadio

    IWCE 2015 presentation. In this work we unravel the effect of dimensionality reduction and the prominent role of surface structure and surface resonances in tuning the phonon dispersion relations and the thermal conductivity of silicon nanostructures, including ultrathin membranes [1], [2] and...

  9. Progress on Quantum Transport Simulation Using Empirical Pseudopotentials

    10 Feb 2016 | Online Presentations | Contributor(s): Jingtian Fang, William Gerard Hubert Vandenberghe, Massimo V Fischetti

    IWCE 2015 presentation. After performing one-dimensional simulation of electron transport in narrow quantum wires without gate control in (Fang et al., 2014) and (Fu and Fischetti, 2013) using the open boundary-conditions full-band plane-wave transport formalism derived in (Fu, 2013), we now...

    07 Feb 2016 | Online Presentations | Contributor(s): Jeffrey Allen

    This talk describes two First-order System Least-squares (FOSLS) formulations of the nonlinear Stokes flow used to model glaciers and ice sheets. The first is a Stress formulation and the second a Stress-Vorticity formulation. Both use fluidity, which is the reciprocal of viscosity and avoid the...
