Nicolau Lopez-Pinto, Christopher Jensen, Zhijie Chen, Zhengwei Tan, Zheng Ma, Maciej Liedke, Maik Butterling, Andreas Wagner, Javier Herrero-Martin, Enric Menendez, Josep Nogues, Kai Liu, Jordi Sort
The increasing energy demand in information technologies requires novel low-power procedures to store and process data. Magnetic materials, central to these technologies, are usually controlled through magnetic fields or spin-polarized currents that are

BIT-FL: Blockchain-Enabled Incentivized And Secure Federated Learning Framework

October 14, 2024
Author(s)
Tao Zhang, Chenhao Ying, Fuyuan Xia, Haiming Jin, Yuan Luo, David Wei, Xinchun Yu, Yibin Xu, Xikun Jiang, Weiting Zhang, Dacheng Tao
Federated learning (FL) enables the protection of data privacy through collaborative training of a machine learning (ML) model without sharing local data. However, several common problems arise when designing FL frameworks, as they rely on a central server

A Guide to the Smart Investment Tools

October 10, 2024
Author(s)
Douglas Thomas, Joshua D. Kneifel, Purav Parekh
This report serves as a guide to the Smart Investment Tool and Smart Investment Tool Express (SITExpress). These tools aid a user in conducting an investment analysis with a focus on those in the manufacturing industry; however, the methods can be used for

Correlation of Structure and Morphology in an Ethylene-glycol Side-chain Modified Polythiophene via Combined X-ray Scattering and Four-dimensional Scanning Transmission Electron Microscopy

October 10, 2024
Author(s)
Andrew Herzing, Lucas Flagg, Chad R. Snyder, Lee Richter, Jonathan Onorato, Christine Luscombe, Ruipeng Li
We report the results of a combined grazing incidence wide-angle X-ray scattering (GIWAXS) and four-dimensional scanning transmission microscopy (4D-STEM) analysis of the effects of thermal processing on poly(3[2-(2-methoxyethoxy)ethoxy]-methylthiophene- 2

Fast Ground State to Ground State Separation of Small Ion Crystals

October 10, 2024
Author(s)
Tyler Gugliemo, Dietrich Leibfried, Stephen Libby, Daniel Slichter
Rapid separation of linear crystals of trapped ions into different subsets is critical for realizing trapped ion quantum computing architectures where ions are rearranged in trap arrays to achieve all-to-all connectivity between qubits. We introduce a

Path-integral calculation of the third dielectric virial coefficient of helium based on ab initio three-body polarizability and dipole surfaces

October 10, 2024
Author(s)
Giovanni Garberoglio, Allan H. Harvey, Jakub Lang, Michal Przybytek, Michal Lesiuk, Bogumil Jeziorski
We develop a surface for the electric dipole moment of three interacting helium atoms and use it, together with state-of-the-art potential and polarizability surfaces, to compute the third dielectric virial coefficient, Cε, for both 4He and 3He isotopes

Single-Crystalline Covalent Organic Frameworks with Exceptionally High Specific Surface Areas and Gas Storage Capacities

October 10, 2024
Author(s)
Baoqiu Yu, Yu Tao, Xuan Yao, Yucheng Jin, Shan Liu, Tongtong Xu, Hailong Wang, Hui Wu, Wei Zhou, Xin Zhou, Xiao Wang, Xu Ding, Xin Xiao, Yue-Biao Zhang, Jianzhuang Jiang
Single-crystalline covalent organic frameworks (COFs) are highly desirable towards understanding their pore chemistry and functions. Herein, two 50100 μm single-crystalline three-dimensional (3D) COFs, TAM-TFPB-COF and TAPB-TFS-COF, were fabricated from

Absence of a Bulk Signature of a Charge Density Wave in Hard X-ray Measurements of UTe2

Caitlin Kengle, Dipanjan Chaudhuri, Xuefei Guo, Thomas Johnson, Simon Bettler, Wolfgang Simeth, Matthew Krogstad, Zahir Islam, Sheng Ran, Shanta Saha, Johnpierre Paglione, Nicholas Butch, Eduardo Fradkin, Vidya Madhavan, Peter Abbamonte
The long-sought pair density wave (PDW) is an exotic phase of matter in which charge density wave (CDW) order is intertwined with the amplitude or phase of coexisting, superconducting order. Originally predicted to exist in copper-oxides, circumstantial

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
