Optical Lattice Clocks

January 1, 2015
Author(s)
Andrew D. Ludlow, Christopher W. Oates
Here we introduce and give a basic description of optical lattice clocks. We also briefly describe recent advances in these atomic frequency standards, looking to future work and applications.

Particle-based simulation of nanoscale systems and materials

January 1, 2015
Author(s)
Alexander Y. Smolyanitsky, Vinod K. Tewary
This book chapter is focused on the introduction of molecular dynamics (MD) and molecular statics (MS), as well as some of their uses for studying the thermomechanical and (indirectly) electronic properties at the nanoscale. We first introduce the general

Rapid DNA melting analyses using a microfabricated electrochemical platform

January 1, 2015
Author(s)
Zuliang Shen, Stephen Semancik, Herman O. Sintim
A new microscale platform is reported which is based on microfabrication methods that integrate thermal control and multi-electrode components to enable rapid temperature-dependent electrochemical measurements on small volume fluid samples. We demonstrate

Atomic Clock with 1x10 -18 Room-Temperature Blackbody Stark Uncertainty

December 31, 2014
Author(s)
Kyle P. Beloy, Nathan M. Hinkley, Nate B. Phillips, Jeffrey A. Sherman, Marco Schioppo, John H. Lehman, Ari D. Feldman, Leonard M. Hanssen, Christopher W. Oates, Andrew D. Ludlow
The Stark shift due to blackbody radiation (BBR) is a key factor limiting the performance of many atomic frequency standards, with the BBR environment inside the clock apparatus being difficult to characterize at a high level of precision. Here we

Monitoring Techniques for the Net-Zero Energy Residential Test Facility

December 31, 2014
Author(s)
Mark W. Davis, William M. Healy, Matthew Boyd, Lisa Ng, William V. Payne, Harrison Skye, Tania Ullah
NIST has constructed a Net-Zero Energy Residential Test Facility that will be used as a testbed for investigating the measurement science related to systems, components, and operations that will lead to homes that generate as much energy over a course of a
