Researchers have discovered that phasons, low-temperature quasiparticles found in crystal lattices, enable interlayer excitons to move at very low temperatures, when motion should stop. In addition to contributing to foundational materials science knowledge, this discovery could help improve the stability of quantum technologies, such as using excitons as qubits.
A new data release from the Dark Energy Spectroscopic Instrument is now available for researchers to explore. The collection contains information on 18.7 million galaxies, quasars, and stars 鈥� the largest dataset of its kind ever shared.
The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining the DESI data with other experiments shows signs that the impact of dark energy may be weakening over time 鈥� and the standard model of how the universe works may need an update.
Scientists have discovered 鈥渂erkelocene,鈥� the first organometallic molecule to be characterized containing the heavy element berkelium. The breakthrough disrupts long-held theories about the chemistry of the elements that follow uranium in the periodic table.
A new study led by researchers at Berkeley Lab outlines a way to engineer pseudo-bonds in materials. Instead of forming chemical bonds, which is what makes epoxies and other composites so tough, the chains of molecules entangle in a way that is fully reversible.
Using super-sensitive detectors smaller than a stamp, a new experiment is searching for dark matter at masses no other experiment has explored.
Scientists encased nanodiamonds in tiny moving droplets of water to improve quantum sensing. The new technique lets researchers detect trace amounts of certain ions and molecules, and could someday find applications in environmental monitoring, medicine, bioengineering, and more.
QSA plays a critical role in supporting the missions of the DOE鈥檚 Advanced Scientific Computing Research (ASCR) program.
Researchers have developed a new optical computing material from photon-avalanching nanoparticles. The breakthrough offers a path toward realizing smaller, faster components for next-generation computers.
Berkeley Lab鈥檚 Advanced Light Source and Molecular Foundry provided powerful tools to study asteroid samples returned by NASA鈥檚 OSIRIS-REx mission. Researchers found that asteroid Bennu contained a set of salty mineral deposits that formed in an exact sequence when a brine evaporated, leaving clues about the type of water that flowed billions of years ago.
Paul Alivisatos, a world-renowned chemist and president of the University of Chicago who served as director of the U.S. Department of Energy鈥檚 Lawrence Berkeley National Laboratory (Berkeley Lab) from 2009 to 2016, has been named one of this year鈥檚 winners of the Enrico Fermi Presidential Award.
With dual lasers, researchers at the Berkeley Lab Laser Accelerator Center accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a 鈥渇rame-by-frame鈥� look at how a petawatt laser interacts with a long plasma channel, knowledge that鈥檚 crucial for building future compact particle accelerators.
Berkeley Lab and several collaborating institutions have successfully demonstrated a machine-learning technique to accelerate discovery of materials for film capacitors 鈥� crucial components in electrification and renewable energy technologies.
Undocumented orphaned wells pose hazards to both the environment and the climate. Scientists are building modern tools to help locate, assess, and pave the way for ultimately plugging these forgotten relics.
Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory of general relativity predicts.
Researchers have taken direct images of the Wigner molecular crystal, a new quantum phase of an electron solid. The breakthrough may advance future technologies for quantum simulations.
Retrofitting a portion of the US shipping fleet from internal combustion engines to battery-electric systems could significantly reduce greenhouse gas emissions and be largely cost effective by 2035, according to a new study from Berkeley Lab researchers.
A difficult-to-describe nanoscale object called the magnetic skyrmion might one day yield new microelectronic devices that can do much more鈥攆or example, massive data storage鈥攁ll while consuming much less power. But researchers need a more detailed understanding of skyrmions if they are ever to be used reliably in computational devices, including quantum computers. Berkeley Lab scientists led a project to make 3D X-ray images of skyrmions that can characterize or measure the orientations of spins inside the whole object.
QSA is breaking new ground in particle physics and promoting interdisciplinary teamwork to address critical scientific challenges.
Amid various efforts to develop algorithms and technologies that close the gap between today's noisy quantum systems and future fault-tolerant quantum computers, QSA researchers from partner institutions have concentrated on using quantum devices and novel techniques for significant applications such as complex molecular simulations in chemistry.
