Restricting Orbital Angular Momentum by Transverse Coherence

September 5, 2020
Author(s)
Ronald L. Cappelletti, John T. Vinson
A traveling wave or wave packet may possess orbital angular momentum in the form of a phase vortex about its axis of propagation. These orbital angular momentum states are a general wave phenomenon, and, as such, can be realized for individual wave packets

Report on the First-Generation NIST Convective Heat Flux Calibration Facility

December 10, 1998
Author(s)
David G. Holmberg, C A. Womeldorf
The National Institute of Standards and Technology has developed a convective heat flux calbration facility to allow evaluation of heat flux sensors. This facility is a small wind tunnel that produces a two-dimensionl laminar boundary layer across a heated

Certification of Standard Reference Material(R) 1450e Fibrous Glass Board

April 17, 2020
Author(s)
Robert R. Zarr, Nathanael A. Heckert
Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450e, Fibrous Glass Board. The meas-urements have been conducted in accordance with a randomized full factorial

Robust Two-Qubit Geometric Phase Gates using Amplitude and Frequency Ramping

November 18, 2025
Author(s)
Christina Bowers, Deviprasath Palani, John Barta, Tyler Guglielmo, Stephen Libby, Dietrich Leibfried, Daniel Slichter
We demonstrate a method for generating entanglement between trapped atomic ions based on adiabatically ramped state-dependent forces. By ramping both the amplitude of the state-dependent force and the motional mode frequencies, we realize an entangling

Optical Atomic Clocks
