From high atop a mountain in the Chilean Andes, the Dark Energy Camera has snapped more than one million exposures of the southern sky. The images have captured around 2.5 billion astronomical objects, including galaxies and galaxy clusters, stars, comets, asteroids, dwarf planets and supernovae.
Scientists recently tested the ability of three techniques called entanglement witnesses to accurately identify pairs of entangled magnetic particles. Of the three, quantum Fisher information (QFI) performed best, routinely locating entanglement in complex materials. This work is the most thorough examination of QFI’s capabilities to date and is the first to apply QFI to massive solid materials.

The quarks and gluons in a proton and their interaction determine the proton’s structure. This structure deforms when exposed to external electric and magnetic (EM) fields, a phenomenon known as polarizability. Scientists use Effective Field Theories (EFTs) to link the description of neutron structure and polarizability to theories of the strong neutron force. In this research, scientists validated EFTs using proton Compton scattering.

Physicists have observed a narrow proton-decaying resonance in beryllium-11. This result supports evidence that the beta-delayed proton decay of beryllium-11 is a sequential two-step process where a near-threshold resonance in beryllium-11 is populated first in a beta decay with a subsequent proton emission.

Subsurface permeability is a key parameter of subsurface flow and transport processes in watersheds, but it is difficult and expensive to measure directly at the scale and resolution required by watershed models. This study used deep learning to accurately estimate the subsurface permeability of a watershed using widely available stream discharge data.

Nuclear physicists have experimentally confirmed the existence of the tetraneutron, a meta-stable nuclear system that can decay into four free neutrons. Researchers have predicted the tetraneutron’s existence since 2016. The new results, which agree with predictions from supercomputer simulations, will help scientists understand atomic nuclei, neutron stars, and other neutron-rich systems.
