Light speed. Less than 1000 m/s.
Researchers at TU Wien were the first to successfully detect Weyl particles in strongly correlated electron systems - that is, materials where the electrons have a strong interaction with each other. In materials like this, the Weyl particles move extremely slowly, despite having no mass. "The strong interactions in such materials usually lead, via the…

Quantum entanglement in living organisms? The complexity of simple definitions.
Researchers managed to generate and study quantum entanglement in living organisms. In the study, scientists used green fluorescent proteins, which are responsible for bioluminescence and commonly used in biomedical research. The research team attempted to entangle the photons generated from the fluorescing molecules within the algae's barrel-shaped protein structure by exposing them to spontaneous four-wave…

Few bodies problem…
In physics, the conundrum known as the "few-body problem," how three or more interacting particles behave, has bedeviled scientists for centuries. Equations that describe the physics of few-body systems are usually unsolvable and the methods used to find solutions are unstable. There aren't many equations that can probe the wide spectrum of possible few-particle dynamics.…

Detecting shadows…
One professor who studies the earth and one who studies space came together in the pursuit to detect and define dark matter. They are one step closer. Using 16 years of archival data from GPS satellites that that orbit the earth, the University of Nevada, Reno team, Andrei Derevianko and Geoff Blewitt in the College…

Growing universe. Creating dimensions…
An international team of physicists has developed an out-of-the-box theory which proposes that shortly after it popped into existence 13.8 billion years ago the universe was filled with knots formed from flexible strands of energy called flux tubes that link elementary particles together. The idea provides a neat explanation for why we inhabit a three-dimensional…
