Top Dark Matter Candidate Loses Ground to Tiniest Competitor
...neutron stars. Together these teams may someday cover most of the possible frequencies. A discovery would permanently rewrite the laws of particle physics and cosmology, but today axions remain entirely...
Quantum Complexity Tamed by Machine Learning
If scientists understood exactly how electrons act in molecules, they’d be able to predict the behavior of everything from experimental drugs to high-temperature superconductors. Following decades of physics-based insights, artificial...
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
...Researchers say that the new understanding forges links between disparate areas of quantum physics and that it could prove useful in experiments that use sensitive photon detectors. The paper is...
It Might Be Possible to Detect Gravitons After All
...hypothetical particle thought to carry the force of gravity — is the ultimate physics experiment. Conventional wisdom, however, says it can’t be done. According to one infamous estimate, an Earth-size...
The New Thermodynamic Understanding of Clocks
Studies of the simplest possible clocks have revealed their fundamental limitations — as well as insights into the nature of time itself. In 2013, a masters student in physics named...
Physicists Spot Quantum Tornadoes Twirling in a ‘Supersolid’
...predictions, but the images alone are a satisfying validation, he said. “This is very relevant for the whole physics community.” Hertkorn wants to see the results replicated by other groups...
New Kind of Magnetism Spotted in an Engineered Material
...theoretical physicists at the Institute for Theoretical Physics, he wants to explore whether kinetic mechanisms like those at play within the moiré material could be used to manipulate charged particles...
Solution: ‘Is It Turtles All the Way Down?’
While the age-old chicken-and-egg paradox is easily answered, the question of infinite regress in physics is far from resolved. In February’s puzzle column, we explored some ways in which science...
Neutron-Star Collision Shakes Space-Time and Lights Up the Sky
...questions in astrophysics. “In one fell swoop, gravitational wave measurements” have opened “a window onto nuclear astrophysics, neutron star demographics and physics and precise astronomical distances,” said Scott Hughes, an...
