Absence of a Bulk Thermodynamic Phase Transition to a Density Wave Phase in UTe2

October 9, 2024
Author(s)
Florian Theuss, Avi Shragai, Gael Grissonnanche, Luciano Peralta, Gregorio de la Fuente Simarro, Ian Hayes, Shanta Saha, Yun Eo, Alonso Suarez, Andrea Capa Salinas, Ganesh Pokharel, Stephen Wilson, Nicholas Butch, Johnpierre Paglione, B. Ramshaw
Competing and intertwined orders are ubiquitous in strongly correlated electron systems, such as the charge, spin, and superconducting orders in the high-Tc cuprates. Recent scanning tunneling microscopy (STM) measurements provide evidence for a charge

Forecasting demand data for critical materials

October 9, 2024
Author(s)
Kyle Foster, Nehika Mathur
Gallium, Indium and Cobalt are critical materials that vital to ramping up the adoption of clean energy technologies such as solar photovoltaics (PVs), electric vehicles (EVs) and wind turbines (WTs). Like other critical materials, they too are prone to

On Comparing Interference Impacts

October 9, 2024
Author(s)
Aric Sanders, Michelle Pirrone, Keith Forsyth, Adam Wunderlich
Interference between communication systems is a critical issue that can impact performance and operability of devices. A wide range of methods and testbeds have been developed to study susceptibility to interference, and each of these testbeds and their

Phase Transitions in Random Circuit Sampling

October 9, 2024
Author(s)
Sergio Boixo, Rene Peralta
Undesired coupling to the surrounding environment destroys long-range correlations on quantum processors and hinders the coherent evolution in the nominally available computational space. This noise is an outstanding challenge to leverage the computation

Gated InAs quantum dots embedded in surface acoustic wave cavities for low-noise optomechanics

October 8, 2024
Author(s)
Zixuan Wang, Ryan DeCrescent, Poolad Imany, Joseph Bush, Sae Woo Nam, Richard Mirin, Kevin L. Silverman
Self-assembled InAs quantum dots (QDs) are promising optomechanical elements due to their excellent photonic properties and sensitivity to local strain fields. Microwave-frequency modulation of photons scattered from these efficient quantum emitters has

Hidden-State Proofs of Quantumness

October 8, 2024
Author(s)
Carl A. Miller
An experimental cryptographic proof of quantumness — that is, a proof, based only on well-studied cryptographic assumptions, that a physical device is performing quantum computations — will be a vital milestone in the progress of quantum information

Self-diffusion of liquid deuterium hydride and liquid tritium

October 8, 2024
Author(s)
T. Prisk, S. Hanna, Richard Azuah
We present a quasi-elastic neutron scattering study of liquid deuterium hydride carried out using the Disk Chopper Spectrometer at the National Institute of Standards and Technology. Under saturated vapor pressure, the self-diffusion constant of deuterium

The Influence of Reorientational and Vibrational Dynamics on the Mg2+ Conductivity in Mg(BH4)2:CH3NH2

October 8, 2024
Author(s)
Mads Amdisen, Yongqiang Cheng, Niina Jalarvo, Daniel Pajerowski, Craig Brown, Torben R. Jensen, Mikael S. Andersson
Reorientational dynamics in solid electrolytes can significantly enhance the ionic conductivity, and understanding these dynamics can facilitate the rational design of improved solid electrolytes. Additionally, recent investigations on metal hydridoborate

Challenges and Opportunities in the Voluntary Carbon Markets

October 7, 2024
Author(s)
Pamela M. Chu, Noah Last, Buddhika Hapuwatte, Clayton Porkorny, Vishal Agrawal
With the increasing need to eliminate carbon dioxide emissions, the voluntary carbon market (VCM) provides a platform to help organizations reach net-zero emission goals through the purchase of carbon offsets. Carbon offsets provide a means to compensate

Gravimetric drop-on-demand inkjet deposition for imaging phantoms with traceable activity

October 7, 2024
Author(s)
Sean Jollota, Denis Bergeron, R. Michael Verkouteren, Svetlana Nour, Ryan Fitzgerald, Ohyun Kwon, Jeffrey Radtke, Bryan Bednarz, Brian Miller, Larry DeWerd
Autoradiography can be an important tool in preclinical investigations with alpha-emitting radionuclides. Precise biodistribution studies establish the effectiveness of chemical "targeting" strategies, assuring that the promise of targeted alpha therapy

Speed of Sound for Understanding Metals in Extreme Environments

October 7, 2024
Author(s)
Elizabeth Rasmussen, Boris Wilthan
Knowing material behavior is crucial to successful design, especially given the growing number of next-generation energy, defense, and manufacturing systems operating in extreme environments. Specific applications for materials in extreme environments

Terahertz On-wafer mTRL Calibration Kits For Microelectronics Characterization

October 7, 2024
Author(s)
Jerome Cheron, Robert Jones, Bryan Bosworth, Jeffrey Jargon, Benjamin Jamroz, Ari Feldman
We report accurate small-signal measurements of heterojunction-bipolar-transistors (HBTs) that are characterized with two on-wafer multiline thru-reflect-line (mTRL) calibration kits. The first calibration kit is designed with thin-film microstrip

Visualizing Shockwave Interactions and Sub-Catastrophic Damage in Materials via Mechanophores

October 7, 2024
Author(s)
Polette Centellas, Kyle Mehringer, Andrew Bowman, Katherine Evans, Parth Vagholkar, Travis Thornell, Liping Huang, Sarah Morgan, Christopher Soles, Yoan Simon, Edwin Chan
Understanding the physical and chemical response of materials to impulsive deformation is crucial for applications ranging from soft robotic locomotion to space exploration to seismology. However, investigating material properties at extreme strain rates

On a conjecture that strengthens Kundu's k-factor Theorem

October 6, 2024
Author(s)
James Shook
Let π = (d1, . . . , dn) be a non-increasing degree sequence with even n. In 1974, Kundu showed that if Dk(π) = (d1 − k, . . . , dn − k) is graphic, then some realization of π has a k-factor. For r ≤ 2, Busch et al. and later Seacrest for r ≤ 4 showed that

Dynamics of Residential Indoor Gas- and Particle-Phase Water-Soluble Organic Carbon: Measurements During the CASA Experiment

October 4, 2024

Marc Webb, Glenn Morrison, Karsten Baumann, Jienan Li, Jenna Ditto, Han Huynh, Jie Yu, Kathryn Mayer, Marina Vance, Delphine Farmer, Jonathan Abbatt, Dustin Poppendieck, Barbara Turpin
Previous time-integrated (2 h to 4 h) measurements show that total gas-phase water-soluble organic carbon (WSOCg) is 10 to 20 times higher inside homes compared to outside. However, concentration dynamics of WSOCg and total particle phase WSOC (WSOCp)—are
