Ytterbium Largely Originates from Supernova Explosion, Research Says

A research group headed by Lund University in Sweden has given a vital clue to the origin of the element Ytterbium present in the Milky Way, by revealing that the element mainly originates from supernova explosions.

Cosmic Flashes Pinpointed to a Surprising Location in Space

Astronomers have been surprised by the closest source of the mysterious flashes in the sky known as fast radio bursts. Precision measurements with radio telescopes reveal that the bursts are made among old stars, and in a way that no one was expecting. The source of the flashes, in nearby spiral galaxy M 81, is the closest of its kind to Earth.

ARPES Reveals Dispersive Excitons in the Quasi-One-Dimensional Metallic Trichalcogenide

Excitons, a bound state of an electron and an electron hole, can form when a given material absorbs a photon above its bandgap energy. The photon excites an electron from the valence band into the conduction band, leaving behind a hole. This positively charged hole attracts the electron and the two can become bound by an electrostatic force known as the Coulomb effect-;this results in an exciton.

Rice Researchers Control Ultracold Rydberg Atoms to Imitate Quantum Interactions

The spatial sense of man does not extend outside the well-known three dimensions, but that does not prevent researchers from exploring with whatever lies outside.

Researchers Explore Quantum Phase Transition in High-Pressure Cuprate Superconductors

Science and technology were considerably impacted by the discovery of cuprate high-temperature superconductors in 1986 and remains fascinating the communities of condensed matter physics and material sciences as they host unusual electronic behavior and the greatest ambient-pressure superconducting transition temperature.

Scientists Investigate the Asymmetry of Antimatter in the Proton

The proton is a positively charged particle that exists at the center of every atom. It is a confined complex system of strongly interacting fundamental particles, quarks, and the nuclear force carriers, gluons. Its properties like charge are dominated by an excess of three quarks -; two "up" quarks and one "down" quark, called valence quarks.

KATRIN Experiment Measures Neutrino Mass with Unprecedented Precision

Neutrinos are arguably the most fascinating elementary particle in our universe. In cosmology they play an important role in the formation of large-scale structures, while in particle physics their tiny but non-zero mass sets them apart, pointing to new physics phenomena beyond our current theories. Without a measurement of the mass scale of neutrinos our understanding of the universe will remain incomplete.
