Benchmark Problems for Phase Field Modeling

January 2, 2017
Author(s)
Andrea Jokisaari, P W. Voorhees, Jonathan E. Guyer, James A. Warren, O. G. Heinonen
We present the first set of benchmark problems for phase field models that are being devel- oped by the Center for Heirarchical Materials Design (CHiMaD) and the National Institute of Standards and Technology (NIST). While many scientific research areas

For IoT to be broadly adopted, it is important to apply the concept to many applications at scale in our everyday life. Using these advanced technologies, our communities and cities can be more intelligent, secure, and resilient. The Hardware and

Cycle Basis Markov Chains for the Ising Model

January 1, 2017
Author(s)
Noah S. Streib, Amanda A. Streib
The ferromagnetic Ising model with zero applied field reduces to sampling even subgraphs X of a graph G with probability proportional to $\lambda^|E(X)|}$, for $\lambda \in [0,1]$. In this paper, we present a class of Markov chains for sampling subgraphs

Gas-phase broadband spectroscopy using active sources: progress, status, and applications

January 1, 2017
Author(s)
Kevin C. Cossel, Eleanor M. Waxman, Ian A. Finneran, Geoffery A. Blake, Jun Ye, Nathan R. Newbury
Broadband spectroscopy is an invaluable tool for measuring multiple gas-phase species simultaneously. In this work we review current applications for broad-band spectroscopy. We discuss components of broad-band spectroscopy including light sources

Tailoring Exchange Couplings in Magnetic Topological Insulator/Antiferromagnet Heterostructures

January 1, 2017
Author(s)
Qing Lin He, Xufeng Kou, Alexander Grutter, Gen Yin, Lei Pan, Xiaoyu Che, Yuxiang Liu, Tianxiao Nie, Bin Zhang, Steven M.T. Disseler, Brian Kirby, William D. Ratcliff, Qiming Shao, Koichi Murata, Xiaodan Zhu, Guoqiang Yu, Yabin Fan, Mohammad Montazeri, Xiaodong Han, Julie Borchers, Kang L. Wang
Magnetic topological insulators such as Cr-doped (Bi,Sb) 2Te 3 provide a platform for the realization of versatile time-reversal symmetry-breaking physics. By constructing heterostructures with the unique Neel order in an antiferromagnetic CrSb and the

Ultra-stable optical clock with two cold-atom ensembles

January 1, 2017
Author(s)
Marco Schioppo, Roger Brown, Will McGrew, Nathan M. Hinkley, Robert J. Fasano, Kyle Beloy, Gianmaria Milani, Daniele Nicolodi, Jeffrey Sherman, Nate B. Phillips, Christopher W. Oates, Andrew Ludlow
Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of atomic interrogation with ‘dead' time required for quantum state preparation and readout. This

An Ideal Solid Solution Model for C-S-H

December 30, 2016
Author(s)
Jeffrey W. Bullard, George W. Scherer
A model for an ideal solid solution, developed by Nourtier-Mazauric et al. [Oil & Gas Sci. Tech. Rev. IFP, 60 [2] (2005) 401], is applied to calcium-silicate-hydrate (C-S-H). Fitting the model to solubility data for C-S-H yields reasonable values for the
