Giant radio pulses from pulsars are hundreds of times more energetic than previously believed

“A group led by scientists from the RIKEN Cluster for Pioneering Research, using coordinated observations of the Crab pulsar in a number of frequencies, have discovered that the “giant radio pulses” which it emits include an increase in x-ray emissions …

Thin cuprous iodide film will enable better optoelectronic devices

“A defect-free thin film of cuprous iodide—made up of just one crystal—has been fabricated by RIKEN physicists1. The atomically flat sample is a boost for producing better semiconductors. Semiconductors lie at the heart of many optoelectronic devices including …

A shapeshifting material based on inorganic matter

“By embedding titanium-based sheets in water, a group led by scientists from the RIKEN Center for Emergent Matter Science has created a material using inorganic materials that can be converted from a hard gel to soft matter using temperature changes …

Dark-matter candidate could display stringy effects in the lab

“Calculations show how theoretical ‘axionic strings’ could create odd behavior if produced in exotic materials in the lab A hypothetical particle that could solve one of the biggest puzzles in cosmology just got a little less mysterious. A RIKEN physicist …

Researchers find “missing link” between magnetars and rotation-powered pulsars

“Researchers from the RIKEN Cluster for Pioneering Research have made observations of a new magnetar, called Swift J1818.0-1607, which challenges current knowledge about two types of extreme stars, known as magnetars and pulsars. The research, just published in The …

Japan’s Fugaku gains title as world’s fastest supercomputer

“The supercomputer Fugaku, which is being developed jointly by RIKEN and Fujitsu Limited based on Arm® technology, has taken the top spot on the Top500 listThe webpage will open in a new tab., a ranking of the world’s fastest …

Scientists succeed in measuring electron spin qubit without demolishing it

“A group of scientists from the RIKEN Center for Emergent Matter Science in Japan have succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD), without changing the spin in the process. This …

Nuclear “magic numbers” collapse beyond the doubly magic Nickel 78

“An international collaboration led by scientists from the University of Hong Kong, RIKEN (Japan), and CEA (France) have used the RI Beam Factory (RIBF) at the RIKEN Nishina Center for Accelerator-base Science to show that 34 is a “magic number …

Quantum interferometry demonstrated in silicon at more practical temperatures

“A silicon-based transistor that displays quantum interference effects at useful temperatures paves the way for highly sensitive sensors Using a silicon-based transistor similar to those found in everyday electronics, RIKEN researchers have produced a functional quantum ‘qubit’—the quantum equivalent …

Superconductor films convert heat into electricity

“Films of a superconductor show excellent thermoelectric properties at very low film thicknesses When thinned down to a sheet a few atoms thick, the superconductor iron selenide (FeSe) can efficiently convert heat into electricity, researchers at RIKEN have discovered1. This …
