A quantitative model for the bipolar amplification effect: A new method to determine semiconductor/oxide interface state densities

October 6, 2021

Author(s)

James Ashton, Stephen Moxim, Ashton Purcell, Patrick Lenahan, Jason Ryan

We report on a model for the bipolar amplification effect (BAE), which enables defect density measurements utilizing BAE in metal-oxide-semiconductor field-effect transistors (MOSFETs). BAE is an electrically detected magnetic resonance (EDMR) technique

Structure and conformational properties of perfect nanogel particles in athermal solutions

October 5, 2021

Author(s)

Alexandros Chremos, Ferenc Horkay, Jack F. Douglas

Conformational properties of 'perfect' nanogel particles having a lattice network topology by molecular dynamics simulations to quantify the inﬂuence of polymer topology on the solution properties of this type of branched molecular architecture. In

Structure and Dynamics of Star Polymer Films from Coarse-Grained Molecular Simulations

October 5, 2021

Author(s)

Jack F. Douglas, Wengang Zhang, Francis W. Starr, Alexandros Chremos

We quantify the structure and dynamics in molecular simulations of star polymer films of varying arm mass Ma and number of star arms f on a supporting solid substrate with an attractive interaction and compare to the corresponding properties of thin films

Bidirectional reflectance capabilities of the NIST Robotic Optical Scattering Instrument (ROSI)

October 1, 2021

Author(s)

Heather Patrick, Catherine Cooksey, Thomas A. Germer, Maria E. Nadal, Clarence Zarobila

The NIST Robotic Optical Scattering Instrument (ROSI) serves as the national reference instrument for specular and diffuse bidirectional reflectance measurements in the ultraviolet (UV) to short-wave infrared (SWIR) wavelength regions. This paper gives a

Three-dimensional dipolar thermalization in a reactive molecular gas with resonant shielding

October 1, 2021

Author(s)

Jun-Ru Li, William Tobias, Kyle Matsuda, Calder Miller, Giacomo Valtolina, Luigi De Marco, Rueben Wang, John Bohn, Goulven Quemener, Jun Ye

We demonstrate suppression of the reactive loss in a gas of ultracold 40K 87Rb molecules in a three-dimensional geometry. The electric field-induced collisional shielding suppresses loss by two orders of magnitude while preserving elastic, long-range

DETERMINATION OF DISTORTION CORRECTIONS FOR A FIXED LENGTH OPTICAL CAVITY PRESSURE STANDARD

September 30, 2021

Author(s)

Jacob Edmond Ricker, Jay H. Hendricks, Kevin O. Douglass, Sarah White, Sergei Syssoev

Optical gas refractometry has enabled new pressure standards to be developed based on a dual Fixed Length Optical Cavity (FLOC) system. NIST in partnership with MKS Instruments has created a portable FLOC pressure standard based gas refractivity. A key

High-Precision Hy-CI and E-Hy-CI studies of Atomic and Molecular Properties

September 29, 2021

Author(s)

James S. Sims, Maria Ruiz, Bholanath Padhy

This review presents a survey of the most important achievements in atomic and molecular calculations obtained with the Hylleraas-configuration interaction method (Hy-CI) and its extension the exponentially correlated Hylleraas-configuration interaction

Collective P-Wave Orbital Dynamics of Ultracold Fermions

September 28, 2021

Author(s)

Mikhail Mamaev, Peiru He, Thomas Bilitewski, Vijin Venu, Joseph Thywissen, Ana Maria Rey

We introduce a protocol to observe p-wave interactions in ultracold fermionic atoms loaded in a 3D optical lattice. Our scheme uses specific motionally excited band states to form an orbital subspace immune to band relaxation. A laser dressing is applied

Complexity of Fermionic Dissipative Interactions and Applications to Quantum Computing

September 24, 2021

Author(s)

Oles Shtanko, A Deshpande, Paul S. Julienne, Alexey Gorshkov

Continuous radio-frequency electric-field detection through adjacent Rydberg resonance tuning

September 24, 2021

Author(s)

MATTHEW SIMONS, Aly Artusio-Glimpse, chris holloway, Eric Imhof, Steven Jefferts, Robert Wyllie, Brian Sawyer, Thad Walker

We demonstrate the use of multiple atomic-level Rydberg-atom schemes for continuous frequency detection of radio-frequency (RF) fields. Resonant detection of RF fields by electromagnetically induced transparency and Autler-Townes (AT) splitting in Rydberg

Asymmetric Blockade and Multiqubit Gates via Dipole-Dipole Interactions
