100 Years of Quantum Mechanics: From Heisenberg's Letter to the Standard Model

2025-07-14

On July 9, 1925, Werner Heisenberg's letter to Wolfgang Pauli marked the beginning of modern quantum mechanics. A century ago, Heisenberg's work on Helgoland Island laid the foundation for modern quantum mechanics. In his letter, Heisenberg abandoned the classical atomic orbital model, focusing instead on experimental observations and laying the groundwork for matrix mechanics. Today, quantum mechanics has evolved into the most precise framework in the history of science—the Standard Model of particle physics—and shows immense potential in quantum sensing and quantum simulation. However, its fundamental interpretation remains controversial, sparking continued exploration and debate.

CERN Performs First Autopsy on Radioactive Beam Dump

2025-05-24

For the first time, CERN performed an autopsy on a radioactive beam dump to investigate nitrogen leaks. After ten years of operation, the dump showed signs of degradation. Engineers overcame the challenges of the high-radiation environment using robots and automated circular saws to dissect the dump's housing and examine its high-density, low-density, and extruded graphite components. Cracks were found in the extruded graphite, but the low- and high-density graphite were in good condition. This autopsy provided valuable data for LHC Run 3 and future HL-LHC beam dump designs, leading to improvements in spare dump designs.

CERN Releases Feasibility Study for Future Circular Collider

2025-04-12

After years of intense work, CERN and its international partners have completed a feasibility study for a Future Circular Collider (FCC). The report details various aspects of the potential project, including physics goals, engineering, environmental impact, and cost. The FCC proposes a roughly 91-km circumference particle collider to succeed the Large Hadron Collider (LHC) in the 2040s. Key scientific goals include deeper investigation of the Higgs boson and other fundamental particles, aiming to unlock the universe's secrets. The report estimates the cost of the FCC's electron-positron collider stage at 15 billion Swiss francs, with construction taking about 12 years. The project emphasizes sustainability and public engagement. The report will be reviewed by the CERN Council, which is expected to decide on the FCC's future around 2028.

Smartphone Camera Sensors Revolutionize Antimatter Research

2025-04-07

The AEgIS collaboration, led by the Technical University of Munich, has repurposed smartphone camera sensors to create a detector capable of imaging antiproton annihilations in real time with unprecedented 0.6-micrometer resolution – a 35-fold improvement. This breakthrough, using 60 integrated camera sensors for a total of 3840 megapixels, surpasses previous methods relying on photographic plates. Human analysis of the images, despite its time-consuming nature, proved crucial for achieving this accuracy. This technology opens new avenues for studying low-energy antiparticle annihilation and the gravitational effects on antihydrogen.

Quantum Entanglement Found in CERN's Sheep Flock: Baa-ing the Quantum World

2025-04-01

Scientists at CERN have made a surprising discovery: evidence of quantum entanglement in a flock of sheep that has grazed on the CERN site for over 40 years. Using sophisticated tracking and modeling, researchers found that the brains of individual sheep exhibit quantum entanglement, explaining their uncanny ability to move and vocalize simultaneously, regardless of distance. This discovery opens a new avenue in quantum physics and ovine research, though further investigation is needed to fully confirm the findings.
