Testing the Possible Doubly Magic Nature of Tin-100, Researchers Study the Electromagnetic Properties of Indium Isotopes

Department of Energy, Office of Science — Wed, 19 Mar 2025 20:25:12 EST

Atomic nuclei with "magic numbers" of protons or neutrons in their nuclear shells are extremely stable. Nuclear physicists are especially interested in nuclei with doubly magic numbers--those that have full shells for both protons and neutrons. One example is the tin isotope Sn-100, which has 50 protons and 50 neutrons. To prepare for future work on Sn-100, researchers studied the properties of isotopes of indium as they approached 50 neutrons. This helps to demonstrate how adding single particles changes the properties of a nucleus.

New DESI Results Strengthen Hints That Dark Energy May Evolve

Lawrence Berkeley National Laboratory — Wed, 19 Mar 2025 18:00:00 EST

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 -- and the standard model of how the universe works may need an update.

Unlocking the Passcodes to Manipulate Natural Bacterial Communities

Department of Energy, Office of Science — Mon, 17 Mar 2025 19:50:59 EST

Bacteria commonly produce toxins that are lethal to themselves, but also produce the required antitoxins. These toxin-antitoxin (TA) systems may be useful in modifying bacteria for biotechnology applications, but the systems have unpredictable behavior. A new study of communities instead of individual species makes TA systems easier to understand and use.

Nuclear Physicists Create Scalable Quantum Circuits to Simulate Fundamental Physics

Department of Energy, Office of Science — Fri, 14 Mar 2025 21:05:50 EST

Simulations of equations from the Standard Model of particle physics are too difficult for classical supercomputers. In this research, scientists for the first time created scalable quantum circuits to prepare a simulation of the starting state for a particle accelerator collision to test aspects of strong interactions. The researchers first determined these circuits for small systems using classical computers, then scaled the quantum circuits to a large system on more than 100 qubits of IBM's quantum computers.

Heavy Ligands Unravel New Chemistry for Heavy Elements

Department of Energy, Office of Science — Wed, 12 Mar 2025 20:50:07 EST

The transplutonium actinides are highly radioactive and rare, making them difficult to study. To examine their chemical properties, researchers typically use non-radioactive lanthanides as surrogates. In this study, scientists streamlined the synthesis of transplutonium actinide compounds, which allowed for more accurate direct comparisons of lanthanides and heavy actinide compounds, showing that transplutonium actinides have truly unique properties.

Scientists Take an Important Step Toward Mitigating Errors in Analog Quantum Simulations of Many-Body Problems

Department of Energy, Office of Science — Tue, 11 Mar 2025 09:10:40 EST

Simulations of quantum many-body problems are a challenge for even the most powerful conventional computers. Quantum computing has the potential to solve this challenge using an approach called an analog quantum simulation. To succeed, these simulations need theoretical approximations of how quantum computers represent many-body systems. In this research, nuclear physicists developed a new framework to analyze these approximations and minimize their effects.
