Sunlight creates quantum entanglement once thought to require lasers
Using a new cone-shaped solar concentrator, researchers showed that sunlight can be used to create entangled photons. This could one day enable satellites to create secure encryption keys…
Physicists have confirmed a new mismatch between matter and antimatter
There’s a newfound mismatch between matter and antimatter. And that could bring physicists one step closer to understanding how everything in the universe came to be. For the…
Neutrinos’ maximum possible mass shrinks further
Neutrinos are known to have tiny masses. A new result proclaims the subatomic particles to be even tinier still. The electrically neutral particles, produced in radioactive decays and…
Scientists used a levitating magnet to hunt for dark matter
In a first-of-its-kind test, scientists used a levitated magnet to search for dark matter, the unidentified substance believed to be present throughout the cosmos. If dark matter is…
Muons’ magnetism matches theory, easing an enduring physics conundrum
One of the most enduring mysteries of particle physics may be finally resolved, two new studies suggest. The oddities of muons, subatomic particles that are relatives of electrons,…
This laser would shoot beams of neutrinos, not light
Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously…
A primordial black hole may have spewed the highest energy neutrino ever found
The highest energy neutrino ever detected from space may finally have an origin story. Mathematical analyses suggest that the ghost particle could’ve come from a theoretical object known…
This tiny gold crystal could bring quantum technology out of the deep freeze
A new Nature study establishes a blueprint for engineering future quantum materials that operate under everyday conditions. Credit: LSU Quantum Photonics Group Quantum materials could reshape fields as…
Lasers made muon beams, no massive accelerator needed
Producing the subatomic particles called muons is now a lighter lift than ever before. Several teams of researchers have generated muons using small particle accelerators driven by lasers.…
Earth is bathed in droves of neutrinos spewed by the Milky Way’s stars
The Milky Way could be called “the Neutrino Way.” Its stars produce vast numbers of the subatomic particles. Now, scientists have calculated how many of them should be…
