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

Obituary of Donald Perkins | Particle physics

Particle physicist Donald Perkins, who died at the age of 97, made fundamental discoveries about the structure of the proton and nuclear interactions at extreme energies, first proposing the use of beams of pion particles in the treatment of cancer. His career spanned the birth of particle physics, emerging from studies of cosmic rays in … Read more

The discovery reveals that “brain-like computing” at the molecular level is possible

PCET mechanism. attributed to him: nature materials (2022). DOI: 10.1038/s41563-022-01402-2 A discovery at the University of Limerick in Ireland has revealed for the first time that unconventional computing that resembles a brain at the smallest scale of atoms and molecules is possible. Researchers at the Bernal Institute at the University of Limerick have worked with … Read more

Scientists are closer to solving the mystery of superconducting with applications in medicine, transportation and energy transfer

Spin fluctuations and phonons in La2-xSrxCuO4 (x = 0.22) near Qδ. S(Q, ω) as a function of energy and the wave vector along a path through two unequal wave vectors Qδ = (0.5-δ, 0.5, L) and (0.5, 0.5-, L) (see inset of panel a). The integration ranges are L ∈[ − 1, 1]and b L ∈[3.8, 4.2]. Strong phonons … Read more

Dark matter as an intergalactic heat source

November 18, 2022• Physics 15, 180 Spectra taken from the quasars indicate that the intergalactic gas may have been heated by a form of dark matter called dark photons. KG Lee / Max Planck Institute for Astronomy and C Stark / University of California, Berkeley Cloudy forecast. Light from distant quasars travels through the universe … Read more

An explosion from an object with a magnetic field a thousand trillion times stronger than our sun

So far, we’ve only had close calls of gamma-ray bursts so large, scientists have suggested, that if they occurred within our solar neighborhood (less than 1,000 light-years away) they would likely trigger mass extinctions on Earth. About 440 million years ago, reports natureA nearby gamma-ray burst may have wiped out much life on Earth. Astrophysicists … Read more
