Complete Einstein’s Theories – A Breakthrough in Particle Physics

More than a century after it first appeared, scientists have completed Einstein’s homework on special relativity in electromagnetism. Osaka University researchers show the relativistic contraction of an electric field generated by fast-moving charged particles, as predicted by Einstein’s theory, which could help improve particle and radiation physics research. More than a century ago, one of … Read more

Quantum Breakthrough: Scientists Extend Qubit’s Life

Scientists have shown that they can extend the life of a molecular qubit by changing the surrounding crystal structure to be less symmetric. The asymmetry protects the qubit from noise, enabling it to hold information five times longer than if it existed in a symmetric structure.

Black holes are stronger than thought – magnetic fields reach deeper into galaxies

Artist’s conception of Cygnus A, surrounded by a ring of dust and debris with jets shooting out from its center. Magnetic fields trapping dust near the supermassive black hole at the galaxy’s core are illustrated. This initial study spurred a larger comparison of radio loudness with polarization and was included in the composite data set. … Read more

Covering the cylinder with a magnetic coil tripled its energy output in a nuclear fusion test

(b) X-ray drive measured with an LEH instrument and incident laser powers for magnetized and non-magnetized AuTa4 hohlraum and two non-magnetic hohlraums. “BF” stands for “BigFoot,” which was the name of the previous ignition design. attributed to him: … Read more

Mathematicians solve a long-standing open problem of the so-called three-dimensional Euler singularities

Approximate steady state in the near field. left: profile ω̅; Right: θ̅ x. attributed to him: arXiv (2022). doi: 10.48550/arxiv.2210.07191 The motion of fluids in nature, including the flow of water in our oceans, the formation of hurricanes in our atmosphere, and the airflow surrounding aircraft, has long been described and simulated by what are … Read more

Quantum algorithms save time in calculating electron dynamics

The calculations allow determination of electron density and post-excitation changes with high spatial and temporal resolution. Here, the example of a lithium hydride molecule shows the electron density shift from cyanide (red) to lithium (green) during a laser pulse. Credit: F. Langkabel/HZB The researchers investigated the ability of known fault-tolerant quantum computing algorithms to simulate … Read more
