Saturation in Solar Cells from Ultra-Fast Pulsed-Laser Illumination

June 4, 2016
Author(s)
Tasshi Dennis
We investigate the potential saturation of a silicon solar cell in response to excitation from continuous-wave and ultra-fast pulsed lasers of equivalent average optical power. Because ultra-fast pulsed sources such as the super-continuum laser have very

Virtual Factory Based Data Analytics

June 4, 2016
Author(s)
Sanjay Jain, Guodong Shao, Seungjun Shin
The concept of a virtual factory representation and its use to support data analytics in multiple ways in manufacturing environment are proposed. The proposed virtual factory when implemented can facilitate improvements in manufacturing operations through

Extending Network Security into Virtualized Infrastructure

June 3, 2016
Author(s)
Ramaswamy Chandramouli, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-125B, "Secure Virtual Network Configuration for Virtual Machine (VM) Protection." That publication provides an analysis of various virtual network configuration options

Orbital-Exchange and Fractional Quantum Number Excitations in an f-electron Metal Yb 2 Pt 2 Pb

June 3, 2016
Author(s)
L. S. Wu, W. J. Gannon, I. A. Zaliznyak, A. M. Tsvelik, M. Brockmann, J.-S. Caux, M. S. Kim, Yiming Qiu, John R. Copley, G. Ehlers, A. Podlesnyak, M. C. Aronson
Exotic quantum states and fractionalized magnetic excitations, such as spinons in one-dimensional chains, are generally viewed as belonging to the domain of 3d transition metal systems with spin 1/2. Our neutron scattering experiments on the 4f-electron

Quantum mechanical effects in plasmonic structures with subnanometre gaps

June 3, 2016
Author(s)
Wenqi Zhu, Ruben Esteban, Andrei G. Borisov, Jeremy J. Baumberg, Peter Nordlander, Henri J. Lezec, Javier Aizpurua, Kenneth B. Crozier
Metal nanostructures with nanogap features have proven highly effective as building blocks for plasmonic systems as they can provide a wide tuning range of operating frequencies and large near-field enhancements. It has recently become apparent that

Single-frequency 571 nm VECSEL for photoionization of magnesium

June 3, 2016
Author(s)
Shaun C. Burd, Tomi Leinonen, Jussi-Pekka Penttinen, David T. Allcock, Daniel H. Slichter, Raghavendra Srinivas, Andrew C. Wilson, Micrea Guina, Dietrich G. Leibfried
We report the development of an intracavity-frequency-doubled VECSEL emitting at 571 nm for photoionization of magnesium. The laser employs a V-cavity geometry with a gain chip at the end of one cavity arm and a lithium triborate (LBO) crystal for second

A Quantum Model of Thermodynamic Mechanical Oscillators

June 2, 2016
Author(s)
Jacob M. Taylor, Chiao-Hsuan Wang
We present a quantum mechanical model of a bath of spins coupled to the elasticity of a material. Motivated by understanding the emergence of thermodynamic restoring forces and oscillations, we show our model reproduces the behavior of a variety of
