Tracking down the origin of photons in gamma-ray bursts, article on RIKEN Research by Drs. S. Nagataki & D. Warren
2019-09-17
The photons released by long gamma-ray bursts - the most powerful electromagnetic phenomena in the Universe - originate in the photosphere, the visible portion of the ‘relativistic jet’ emitted by exploding stars, according to simulations by RIKEN researchers.

The shape of circadian rhythm, article on RIKEN Research by Drs. S. Gibo & G. Kurosawa
2019-09-17
The waveforms of circadian cycles in bacteria, flies and mammals become increasingly jagged as the temperature rises, two RIKEN researchers have predicted. This finding is a step toward solving the mystery of how circadian rhythms remain consistent under changing conditions.
Hot Topic
Short Report of Robotics Workshop held at IIAS in Kyoto
2019-09-20
Robotics Workshop organized by RIKEN was held on Sep. 12-13 at a beautiful campus of the International Institute for Advanced Studies (IIAS) in Kyoto.
Gilles Ferrand (ABBL/iTHEMS) and Tetsuo Hatsuda (iTHEMS) attended the workshop: Gilles gave a talk on "Virtual Reality and Robotics" and also conducted VR demo during the coffee breaks with Tetsuo as his assistant. All the 35 talks during the two days were "graphically recorded" in real time as the one attached for the Gilles case. (Some illustration company in Kyoto came to do this.) Although each coffee break was short (5-10 min), altogether six people could enjoy the VR of the supernova remnant. It was an interesting experience for us to interact with robotics engineers who have rather different way of thinking from the researchers in basic sciences.

Topological phases of matter and operator algebras
October 4 (Fri) at 15:30 - 17:00, 2019
Yasuyuki Kawahigashi (Senior Visiting Scientist, iTHEMS / Professor, Graduate School of Mathematical Sciences, The University of Tokyo)
Topological phases of matter are hot topics in recent physics and related to a wide range of mathematical fields. I will talk about their aspects related to operator algebras. Our emphasis will be on theory of tensor categories which describe interactions of anyons. This theory plays an important role in topological quantum computations.
In theory of operator algebras, Jones initiated theory of subfactors and discovered the Jones polynomial, a new topological invariant for knots as an application. We apply this theory to mathematical studies of anyons.

Workshop
Workshop on Virtual Reality[Session 1]
October 7 (Mon) at 13:00 - 16:00, 2019
Gilles Ferrand and Don Warren will run a workshop on using virtual reality (VR) for data visualization and research. Anyone from any RIKEN campus, and any field of study, is welcome. We want to build a cross-disciplinary group of people with a shared interest in VR, and to apply this tool to a broad range of data types and topics.

Researches & Researchers
Knowledge that spreads from many encounters - Ade Irma Suriajaya
2019-09-20
Ade Irma Suriajaya (Chacha) is originally from Indonesia and shifted her field from aeronautical engineering to mathematics. We will introduce the beauty of mathematics, which Chacha has been eager to learn, going so far as to move from Indonesia to China and then onto Japan.
