John von Neumann once said “Anyone who attempts to generate random numbers by deterministic means is, of course, living in a state of sin.” Enter Calvin Leung from Harvey Mudd College in California and colleagues. […]

Tommi Hakala and colleagues of the Aalto University School of Science have made a new type of Bose–Einstein condensate, in which the condensate particles are surface plasmon polaritons – a mixture of light and electrons. […]

For quantum computing to reach its full potential, the critical benchmark to push is the number of quantum-entangled qubits. Nicolai Friis of the Austrian Academy of Sciences and colleagues now report entangled states in a […]

A constant flow of challenging projects, a wealth of in-house expertise and the freedom to explore ideas make CERN a unique laboratory for vacuum technology for particle physics and beyond.

The feature “Putting the Pauli exclusion principle on trial” (CERN Courier March 2018 p35) was extremely interesting, describing highly accurate experiments that have put severe limits on the possible violation of the Pauli principle. Testing […]

Integrated luminosity On 28 April, 13 days ahead of schedule, operators at CERN’s Large Hadron Collider (LHC) successfully injected 1200 bunches of protons into the machine and brought them into collision – formally marking the beginning of […]

The large centre-of-mass energy and luminosity of the LHC have made possible the first measurements of electroweak-boson production in ultrarelativistic heavy-ion collisions. The production cross sections for such processes in proton–proton (pp) collisions are known with high precision, and indeed have

Although barely noticeable in this image of a massive galaxy cluster (left), which was taken with the Hubble Space Telescope, the small blue dot in the centre of the inset could be the farthest star […]

Time crystals – structures whose lowest- energy configurations are periodic in time rather than space – were first experimentally demonstrated in 2017 in (spatially) disordered systems. Two independent teams have now added spin systems periodically […]

“What is the origin of the universe? This very simple question lies at the heart of all your work and forms the basis of the ambitions for the Future Circular Collider study.” – José van Dijck, president of the Royal Netherlands Academy of Arts and Sciences.

Plastic waste Easily recyclable polymers, which could be broken down into their constituent monomers and then repolymerised, would potentially help to solve the global plastic-waste problem. Jian-Bo Zhu and colleagues of Colorado State University have developed a […]

NA62’s candidate event The NA62 collaboration at CERN has found a candidate event for the ultra-rare decay K+ → π+ ν ν, demonstrating the experiment’s potential to test heavily-suppressed corners of the Standard Model (SM). The SM prediction for the K+ → π+ ν ν branching […]
