Researchers test quantum theory with precision-engineered thin films

DOE/US Department of Energy

Comparing experimental results and theoretical calculations can be difficult for quantum materials. One solution is to use sample materials that isolate and emphasize an atomic line with one dimensional properties. In this study, scientists grew thin films of layered copper-oxygen materials to experimentally test theories of electron interaction in quantum materials. The study indicates that standard theory is not sufficient and requires a new term to fit the experimental data.

Department of Energy announces $24 million for research on quantum networks

DOE/US Department of Energy
Grant and Award Announcement

Today, the U.S. Department of Energy (DOE) announced $24 million in funding for three collaborative projects in quantum network research.

Transforming cancer diagnosis and treatment with cerium/lanthanum-134

DOE/US Department of Energy

Actinium-targeted alpha radiotherapy is a promising approach for treating metastatic cancers, including prostate cancer. However, therapeutic substances labeled with actinium-225 have limits on how they can be imaged, a step that allows doctors to plan treatments. This study examined the performance of cerium/lanthanum-134 as a surrogate imaging material for Ac-225.

Calculations predict surprising quark diffusion in hot nuclear matter

DOE/US Department of Energy

Tracking how high energy jets of quarks travel through the quark-gluon plasma (QGP) can reveal information about the QGP’s properties. Recent theoretical calculations that include non-local quantum interactions in the QGP predict a super-diffusive process that deflects energetic particles faster than previously assumed. The discovery might help explain why the QGP flows like a nearly perfect liquid.

DOE announces $126 million for small businesses to pursue clean energy research and development

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) today announced 106 awards totaling $126 million in research and development grants for 90 different small businesses whose projects will address multiple mission areas across the Department, including clean energy and decarbonization, cybersecurity and grid reliability, fusion energy, and nuclear nonproliferation. Small businesses are the backbone of the nation’s economy, employing nearly half of all private-sector workers in the United States, and will play a major role in decarbonizing the economy, bolstering national security, and meeting President Biden’s ambitious climate goals.

Department of Energy announces $16 million for research on scientific machine learning for complex systems

DOE/US Department of Energy
Grant and Award Announcement

Today, the U.S. Department of Energy (DOE) announced $16 million in funding for four projects in scientific machine learning for the predictive modeling and simulation of complex systems.

AtomAI brings deep learning to microscopy data analysis software

DOE/US Department of Energy

Electron and scanning probe microscopes have become critical tools for condensed matter physics, materials science, and chemistry research. However, researchers have lacked infrastructure to establish broad connections between microscopy observations and materials behavior. AtomAI, a new deep learning-based image analysis software package, was designed to help address this gap.

Department of Energy announces $9.96 million for basic plasma science research

DOE/US Department of Energy
Grant and Award Announcement

Today, the U.S. Department of Energy (DOE) announced $9.96 million in funding for universities, private industry, and a national laboratory to support research in basic plasma science and engineering as well as frontier plasma science experiments at several midscale DOE Collaborative Research Facilities (CRFs) across the nation.

New insights into how strange matter interacts with ordinary matter

DOE/US Department of Energy

Scientists reported the first observations of how hypernuclei flow from particle collisions. The researchers observed that the hypernuclei flow much the same as ordinary nuclei in a way that scales with their overall nuclear mass. This implies that hyperons (particles made of at least one strange quark) interact with ordinary protons and neutrons the same way these ordinary nucleons interact with one another when they coalesce to form nuclei.

In preparation for DUNE, scientists examine modern nuclear theory for neutrino oscillation physics

DOE/US Department of Energy

Predictions of neutrino-nucleon interaction made using the Lattice Quantum Chromodynamics (LQCD) nuclear theory method predict stronger interaction than predictions determined from older, less precise experimental data. New research demonstrated important implications of how scientists interpret neutrino oscillation signals from LQCD. The results will help prepare for work at the Deep Underground Neutrino Experiment.
