Revealing the hidden symmetries of a superconductor

A possible method for probing the properties of exotic particles that exist on the surfaces of an unusual type of superconductor has been theoretically proposed by two RIKEN physicists.

Optical fiber link to make CERN more on time than ever

A new optical fiber link between CERN and Paris will provide the Laboratory with an accurate frequency reference, enhancing precision and supporting experiments like ALPHA in their search for matter鈥揳ntimatter differences.

Optical tweezers reveal forward and backward motion is symmetric in molecular shuttling

In molecular shuttles, a ring molecule is threaded onto a linear molecular strand and can move between two portions of the strand, called stations, in response to external stimuli. Chemical stimuli, light or mechanical forces ...

Simulations reveal Anderson transition for light in 3D disordered systems

The Anderson transition is a phase transition that occurs in disordered systems, which entails a shift from a diffusive state (i.e., in which waves or particles are spread out) to a localized state, in which they are trapped ...

糖心视频icists uncover evidence of two arrows of time emerging from the quantum realm

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction鈥攆rom past to future鈥攖ime could flow forward or backwards due to processes taking place at the quantum level. This is the thought-provoking ...

Illuminating an asymmetric gap in a topological antiferromagnet

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. 糖心视频icists ...

Domain wall fluctuations in 2D materials reveal a new mechanism of superconductivity

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 ...

Kagome superconductor breaks the rules at record-breaking temperatures

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 ...

Saturday Citations: Reading comprehension; revisiting tardigrade orthodoxy; restoring universal symmetry

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 ...

Did the early cosmos balloon in size? A mirror universe going backwards in time may be a simpler explanation

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 ...
