On the bending strength of single-crystal silicon theta-like specimens

Author(s)
Rebecca R. Kirkpatrick, William Alexander Osborn, Michael S. Gaither, Richard S. Gates, Frank W. DelRio, Robert F. Cook
A new theta geometry was developed for micro-scale bending strength measurements. The new "gap" theta specimen was a simple modification of the arch theta

Spinor Dynamics in an Antiferromagnetic spin-1 Thermal Bose Gas

Author(s)
Hyewon K. Pechkis, Jonathan Wrubel, Arne Schwettmann, Paul Griffin, Ryan Barnett, Eite Tiesinga, Paul D. Lett
We present experimental observations of coherent spin-population oscillations in a cold thermal, Bose gas of spin-1 23Na atoms. The population oscillations in a

A highly ordered non-crystalline metallic phase

Author(s)
Gabrielle G. Long, Karena Chapman, Peter Chupas, Leonid A. Bendersky, Lyle E. Levine, Frederic Mompiou, John W. Cahn, Judith K. Stalick
We report the characterization of an ordered non-crystalline isotropic metallic solid that, during rapid cooling of an Al-Fe-Si melt, forms by nucleation

Direct Observation of Zitterbewegung in a Bose-Einstein condensate

Author(s)
Lindsay J. LeBlanc, Matthew Beeler, Karina Jimenez-Garcia, Abigail R. Perry, Seiji Sugawa, Ross Williams, Ian B. Spielman
Zitterbewegung, a force-free trembling motion first predicted for relativistic fermions like electrons, was an unexpected consequence of the Dirac equation's

Calibration-Kit Design for Millimeter-Wave Silicon Integrated Circuits

Author(s)
Dylan F. Williams, Phillip Corson, Sharma Jahnavi, Krishnaswamy Harish, Tai Wei, George Zacharias, Ricketts David, Watson Paul, Dacquay Eric, Voinigescu Sorin
We study and present design guidelines for thru-reflect-line vector-network-analyzer calibration kits used for characterizing circuits and transistors

What's in a 'NYM?

Author(s)
Robert R. Keller
The field of electron microscopy, by its very diverse nature, abounds with acronyms: AEM, EF-TEM, ESEM, FE-SEM, HREM, HRTEM, HVEM, SEM, STEM, TEM, and VP-SEM

Parallel Geometric Classification of Stem Cells by Their 3D Morphology

Author(s)
Derek Juba, Antonio Cardone, Cheuk Y. Ip, Carl Simon Jr., Christopher K. Tison, Girish Kumar, Mary C. Brady
Autologous stem cells show great promise for tissue engineering as they can regenerate diseased or damaged tissue, without requiring an organ donor or causing

Demonstration of a dressed-state phase gate for trapped ions

Author(s)
Ting Rei Tan, John P. Gaebler, Ryan S. Bowler, Yiheng Lin, John D. Jost, Dietrich G. Leibfried, David J. Wineland
We demonstrate a trapped ion entangling gate scheme proposed by Bermudez et~al [Phys. Rev. A 85, 040302 (2012)]. Simultaneous excitation of a strong carrier and

99.996% 12C films enriched and deposited in situ

Author(s)
Kevin J. Dwyer, Joshua M. Pomeroy, David S. Simons
A mass selected ion beam system is used to isotopically enrich and deposit thin films, which are measured to be 99.9961(4)% 12C. In solid state quantum
