Gamma-ray laser moves a step closer to reality Posted: 06 Dec 2019 12:29 PM PST A physicist has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser. |
A platform for stable quantum computing, a playground for exotic physics Posted: 05 Dec 2019 10:05 AM PST Researchers have demonstrated the first material that can have both strongly correlated electron interactions and topological properties, which not only paves the way for more stable quantum computing but also an entirely new platform to explore the wild world of exotic physics. |
Posted: 05 Dec 2019 10:05 AM PST A team of computer science professors created a method to quickly resize animations of fluids without having to completely re-simulate the entire sequence. |
Posted: 05 Dec 2019 08:32 AM PST Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One problem is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion could be initiated at lower energies with electromagnetic fields that are generated by state-of-the-art free electron lasers emitting X-ray light. Researchers describe how this could be done. |
Scientists see defects in potential new semiconductor Posted: 05 Dec 2019 08:32 AM PST A research team has reported seeing, for the first time, atomic scale defects that dictate the properties of a new and powerful semiconductor. The study shows a fundamental aspect of how the semiconductor, beta gallium oxide, controls electricity. |
