High-Throughput Nanopore Fabrication and Classification Using Xe-Ion Irradiation and Automated Pore-Edge Analysis

September 26, 2022
Author(s)
Michal Macha, Sanjin Marion, Mukesh Tripathi, Martina Lihter, Alex Smolyanitsky, Andras Kis, Aleksandra Radenovic
Large-area nanopore drilling is a major bottleneck in state-of-the-art nanoporous 2D membrane fabrication protocols. In addition, high-quality structural and statistical descriptions of as-fabricated porous membranes are key to predicting the corresponding

Tightly Confined Surface Acoustic Waves as Microwave-to-Optical Transduction Platforms in the Quantum Regime

September 26, 2022
Author(s)
Ryan DeCrescent, Zixuan Wang, Poolad Imany, Robert Boutelle, Corey McDonald, Travis Autry, John Teufel, Sae Woo Nam, Richard Mirin
Surface acoustic waves (SAWs) coupled to quantum dots (QDs), trapped atoms and ions, and point defects have been proposed as quantum transduction platforms, yet the requisite coupling rates and cavity lifetimes have not been experimentally established

Provably efficient machine learning for quantum many-body problems

September 23, 2022
Author(s)
Hsin-Yuan Huang, Richard Kueng, Giacomo Torlai, Victor Albert, John Preskill
Classical machine learning (ML) provides a potentially powerful approach to solving challenging quantum many-body problems that arise in physics and chemistry, but the advantages of ML over more traditional classical methods have not been firmly

Sub-recoil clock-transition laser cooling enabling shallow optical lattice clocks

September 8, 2022
Author(s)
Xiaogang Zhang, Kyle Beloy, Youssef Hassan, William McGrew, Chun-Chia Chen, Jacob Siegel, Tanner Grogan, Andrew Ludlow
Laser cooling is a key ingredient for quantum control of atomic systems in a variety of settings. In two-valence-electron atoms, two-stage Doppler cooling is typically used to bring atoms to the μK regime. Here, we implement a pulsed radial cooling scheme

Visualizing Localized, Radiative Defects in GaAs Solar Cells

September 1, 2022
Author(s)
Behrang Hamadani, Margaret Stevens, Brianna Conrad, Matthew Lumb, Kenneth Schmieder
We have used a calibrated, wide-field hyperspectral imaging instrument to obtain absolute spectrally and spatially resolved photoluminescence images in high growth-rate, rear-junction GaAs solar cells from 300 K to 77 K. At the site of some localized

Megahertz-rate Ultrafast X-ray Scattering and Holographic Imaging at the European XFEL

August 23, 2022
Author(s)
Thomas J. Silva, Hans Nembach, Mark Keller, Justin Shaw, Nanna Hagstrom, michael schneider, Nico Kerber, Alexander Yaroslavtsev, Erick Parra, Eric Fullerton, Oleg Shpyrko, Christian Gutt, Hermann Durr, Ezio Iacocca, Roopali Kukreja, stefano Bonetti, Emmanuelle Jal
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, from chemistry to biology, giving researchers access to X-rays with unprecedented brightness, coherence, and pulse duration

Relative effects of polymer composition and sample preparation on glass dynamics

August 17, 2022
Author(s)
Christopher Soles, Amanda L. Forster, Katherine Evans, Madhusudan (Madhu) Tyagi, Robert M. Elder, Timothy Sirk, Joseph Dennis, Kanae Ito, Osama Yamamuro, Hiroshi Akiba
Modern design of common adhesives, composites and polymeric parts makes use of polymer glasses that are stiff enough to maintain their shape under a high stress while still maintaining a ductile behavior after the yield point. Typically, material

Effect of Tribologically-Induced Changes in Surface Termination of Silicon-Containing Diamond-Like Carbon Coatings on the Resistance to Biomolecule Adsorption

August 1, 2022
Author(s)
Cherno Jaye, Daniel A. Fischer, Zixuan Li, Jennings Z. Ye, Jieming Yan, Nicolas Molina, Hsu-Ming Lien, Robert Chrostowksi, Jianliang Lin, Mangolini Mangolini
Silicon-containing diamond-like carbon (DLC) is a class of thin-film materials with excellent mechanical properties, high thermal stability, and good tribological performance over a wide range of environmental conditions. While non-alloyed/non-doped DLCs

Individual qubit addressing of rotating ion crystals in a Penning trap

July 25, 2022
Author(s)
Anthony M. Polloreno, Ana Maria Rey, John J. Bollinger
Trapped ions boast long coherence times, and excellent gate fidelities, making them a useful platform for quantum information processing. Scaling to larger numbers of ion qubits, potentially solved by photonic interconnects between Paul traps, or by

Floquet engineering topological Dirac bands

July 22, 2022
Author(s)
Ian Spielman, Mingwu Lu, Amilson R. Fritsch, Graham Reid, Alina Pineiro Escalera
We experimentally realized a time-periodically modulated 1D lattice for ultracold atoms featuring a pair of linear bands, each associated with a Floquet winding number: a topological invariant. These bands are spin-momentum locked and almost perfectly
