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 superconductor RbV3Sb5 at temperatures as high as 175 K. This sets a new record for the temperature at which time-reversal symmetry breaking is observed among Kagome systems.
Why is human culture—the shared body of knowledge passed down across generations—so much more powerful than animal cultures?
Edge computing devices, devices located in proximity to the source of data instead of in large data centers, could perform computations locally. This could reduce latency, particularly in real-time applications, as it would minimize the need to transfer data from the cloud.
The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length contraction and time dilation. If an object travels at a relative speed, which is a non-negligible fraction of the speed of light, with respect to an observer, the length of the object in the travel direction will appear shorter to the observer than it actually is in the object’s rest frame.
Since the launch of the Large Hadron Collider, there has been ongoing research there into Higgs bosons and a search for traces of physics beyond the existing model of elementary particles. Scientists working at the ATLAS detector have combined both goals: with the latest analysis it has been possible to expand our knowledge of the interactions of Higgs bosons with each other, and stronger constraints on the phenomena of “new physics” have been found.
Superconductivity is the phenomenon by which, at sufficiently low temperatures, electric current can flow in a metal with no resistance. While certain metals are excellent superconductors, other metals cannot superconduct at all.
From time to time, when Earth’s tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from deep Earth may have affected the climate over the past billion years.
A Chinese rover has found new evidence to support the theory that Mars was once home to a vast ocean, including tracing some ancient coastline where water may once have lapped, a study said Thursday.
A research team led by Lund University in Sweden has developed an AI tool that traces back the most recent places you have been to. The tool acts like a satellite navigation system, but instead of guiding you to your hotel, it identifies the geographical source of microorganisms.
When it comes to electrically conductive nanomaterials, graphene—stronger and lighter than steel and more conductive than copper—has been shown to be an excellent choice for a wide range of technologies.
