Ketterle Team: "Neutrino Laser" Based on Quantum-Entangled Atomic Clouds Theoretically Infeasible

Nobel laureate Wolfgang Ketterle and his team have conducted a theoretical examination of a neutrino laser concept and concluded that the scheme is fundamentally difficult to realize. The research findings have been published in *Physical Review Letters*. The concept was previously proposed by American physicists, with the core idea being the use of rubidium-87 atomic clouds or other unstable isotopes, placing them into specific quantum states to generate highly directional neutrino beams. According to the concept, if a neutrino source analogous to a laser could be constructed, it would help accelerate neutrino mass measurements and advance observational studies of the interconversion phenomena among different types of neutrinos. The Ketterle team's key focus this time was whether a large number of atoms could cooperatively emit neutrinos and other fermions, similar to the synchronized release of photons in a conventional laser.

Russian Scientists Propose New Scheme for Measuring Proton and Deuteron Electric Dipole Moments in a Single Storage Ring

August 21 news, researchers from the Moscow Institute of Physics and Technology, the Institute for Nuclear Research of the Russian Academy of Sciences, the National Research Nuclear University MEPhI, and the Landau Institute for Theoretical Physics of the Russian Academy of Sciences have proposed a new experimental scheme to study the electric dipole moments of protons and deuterons in a single storage ring. The scheme can be implemented both in specially constructed new facilities and, potentially, in upgraded existing accelerator complexes. The electric dipole moments of protons and deuterons reflect the asymmetry of the internal charge distribution relative to the spin direction. According to Standard Model predictions, their values are non-zero but extremely small, on the order of 10⁻³¹ e·cm, far below current experimental sensitivity...

CERN Large Hadron Collider Data Challenge Models of Oxygen and Neon Nucleus Structure

Physicists at the European Organization for Nuclear Research (CERN), analyzing a new batch of collision data from the CMS detector at the Large Hadron Collider, have found that oxygen and neon nuclei do not behave entirely as predicted by existing models in high-energy collisions. This result indicates that the scientific community's understanding of the shapes and internal structures of certain light nuclei still requires further refinement. In high-energy nuclear collisions, a quark-gluon plasma is briefly formed in the collision region. This state of matter decays rapidly, but the collective flow characteristics of its particles can be used to infer the collision geometry and indirectly provide information about nuclear structure. Researchers believe that symmetric collisions of light ions help better control the initial collision conditions, making them suitable for studying collective responses in small systems.

South Korea Approves Restart of Shin-Kori Unit 1

The Nuclear Safety and Security Commission (NSSC) of South Korea announced on August 21 that it has approved the restart of Shin-Kori Unit 1, located in Ulju County, Ulsan. The unit has been under routine inspection since July 2. On the same day, the commission approved the unit to reach criticality. Criticality refers to the state in which a sustained nuclear fission chain reaction can be maintained within the reactor core, with a balanced neutron population. Once criticality is achieved, the reactor can gradually resume operation under safely controlled conditions. The NSSC stated that this routine inspection involved 98 inspection items required before the reactor could reach criticality, of which 86 have been completed, confirming that the unit meets the conditions for safely achieving criticality.

Large Hadron Collider experiments reveal neon nucleus may be bowling-pin shaped

A recent experimental result from the Large Hadron Collider at CERN suggests that the internal structure of the neon-20 nucleus may not be approximately spherical as commonly depicted in traditional textbooks, but rather closer to a "bowling pin" shape. This finding provides new experimental clues for studying deformation of light atomic nuclei and collective behavior in high-energy nuclear collisions. Atomic nuclei are composed of protons and neutrons, determining the elemental identity of atoms and carrying most of their mass. Although nuclei are often simplistically depicted as spherical, nuclear physics research has shown that some nuclei exhibit pronounced non-spherical deformation, such as the pear-shaped nuclei mentioned in previous studies. Accurately understanding these shapes helps physicists...
