Neutron Interferometry Using a Single Modulated Phase Grating
I. J. Hidrovo, J. Dey, H. Meyer +5
Neutron grating interferometry provides information on phase and small-angle scatter in addition to attenuation. Previously, phase grating moiré interferometers (PGMI) with two- or…
Strong equilibration of Landau levels edge-states at the graphene edge
Son T. Le, Joseph A. Hagmann, Nikolai Klimov +4
We present the results of an experimental study of the interaction of quantized Landau level (LL) edge-states at the physical edge of graphene by using a graphene pn junction devic…
Single-beam Zeeman slower and magneto-optical trap using a nanofabricated grating
D. S. Barker, E. B. Norrgard, N. N. Klimov +3
We demonstrate a compact (0.25 L) system for laser cooling and trapping atoms from a heated dispenser source. Our system uses a nanofabricated diffraction grating to generate a mag…
Challenges to miniaturizing cold atom technology for deployable vacuum metrology
Stephen Eckel, Daniel S. Barker, James A. Fedchak +3
Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of…
Quantum-based vacuum metrology at NIST
Julia Scherschligt, James A. Fedchak, Zeeshan Ahmed +10
The measurement science in realizing and disseminating the unit for pressure in the International System of Units (SI), the pascal (Pa), has been the subject of much interest at th…
Development of a new UHV/XHV pressure standard (cold atom vacuum standard)
Julia Scherschligt, James A Fedchak, Daniel S Barker +4
The National Institute of Standards and Technology has recently begun a program to develop a primary pressure standard that is based on ultra-cold atoms, covering a pressure range…
