What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level. This is the thought-provoking ...
Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their surfaces conduct electricity, yet their interiors do not, instead acting as insulators. Â鶹ÒùÔºicists ...
Two-dimensional (2D) van der Waals are made of atomically thin layers, held together by weak van der Waals forces. These materials have been the focus of numerous studies, as their unique properties make them ideal for studying ...
Using muon spin rotation at the Swiss Muon Source SmS, researchers at the Paul Scherrer Institute (PSI) have discovered that a quantum phenomenon known as time-reversal symmetry breaking occurs at the surface of the Kagome ...
This week, physicists suggested that quantum entanglement may be really, really fast rather than instantaneous, and could be measured at an attosecond scale. Paleontologists discovered a fossilized mammal in Colorado that ...
We live in a golden age for learning about the universe. Our most powerful telescopes have revealed that the cosmos is surprisingly simple on the largest visible scales. Likewise, our most powerful "microscope," the Large ...
Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary. For that, they must ...
Generative AI systems, such as ChatGPT, are trained on large datasets to create written, visual or audio content in response to prompts. When fed real images, some algorithms can produce fake photos and videos known as deepfakes.
In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets. These materials exhibit a unique type of magnetism that differs from both conventional ...
As our digital world generates massive amounts of data—more than 2 quintillion bytes of new content each day—yesterday's storage technologies are quickly reaching their limits. Optical memory devices, which use light ...
