Unexpected Exciton Mobility at Cryogenic Temperatures: Phasons in Moiré Superlattices

2025-03-28

Researchers at Berkeley Lab have discovered that phasons, low-temperature quasiparticles in moiré superlattices, enable interlayer excitons to move even at extremely low temperatures where motion should cease. This challenges conventional understanding and opens new avenues for improving the stability of quantum technologies by leveraging excitons as qubits. The discovery, made possible by the Molecular Foundry's Imaging and Manipulation of Nanostructures facility, provides fundamental insights into materials science and offers a promising path forward for quantum information science.

Groundbreaking Discovery: First Organometallic Molecule Containing Berkelium Synthesized

2025-03-27

A team at the Department of Energy’s Lawrence Berkeley National Laboratory has successfully synthesized "berkelocene," the first characterized organometallic molecule containing the heavy element berkelium. This breakthrough challenges long-held theories about the chemistry of elements following uranium in the periodic table. The synthesis was incredibly challenging due to berkelium's high radioactivity and air sensitivity. The researchers overcame these hurdles using specialized equipment and a mere 0.3 milligrams of berkelium-249. This discovery provides new insights into the chemical behavior of berkelium and other actinides, opening doors for future research.

DESI Releases First Data Release, Opening Up a Universe of Possibilities
