Latest calculation based on how subatomic muons interact with all known particles comes out just in time for comparison with precision measurements at new 'Muon g-2' experiment.

Australian scientists have achieved a new milestone in their approach to creating a quantum computer chip in silicon, demonstrating the ability to tune the control frequency of a qubit by engineering its atomic configuration. The work has been published in Science Advances.

An international team of scientists that includes UC Riverside physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM.

EPFL physicists have now demonstrated experimentally the ability to coherently manipulate the wave function of a free electron down to the attosecond timescale (10-18 of a second). The team also developed a theory for creating zeptosecond (10-21 of a second) electron pulses, which could also be used to increase the energy yield of nuclear reactions.

Observations made by researchers using a National Science Foundation (NSF) detector at the South Pole and verified by ground- and space-based telescopes have produced the first evidence of one source of high-energy cosmic neutrinos.

A group of researchers from Aalto University in Finland and Sun Yat-sen University in China provide a standardized approach to improve the accuracy and reliability of contact angle measurements of surfaces.
