From May 31 to June 3, Journalist in Residence Workshop 2019 was held at Tambara Institute of Mathematical Sciences of the University of Tokyo. As for the "Journalist in Residence (JIR)" program in Mathematics and the Journalist in Residence Workshop please look at iTHEMS Newsletter vol 10. This year, there were 11 journalists and 10 participants from RIKEN, 3 from universities and 6 from others. 8 iTHEMS members mainly explained their working field and recent important achievements to the nonspecialists. There were 25 talks in a variety of fields. They were very interesting but the schedule was a little tight. The discussion among the participants continued with joy until very late in the evening as usual. The participants are grateful to the staff of Tambara Institute as well as to the iTHEMS assistants for the great help to organize the workshop.

Seminar Report

Seminar by Professor Yasunori Nomura from Berkeley

2019-06-07

Prof. Yasunori Nomura from Berkeley Center for Theoretical Physics, for which Prof. Nomura serves as the director, gave a seminar entitled " Quantum Mechanics of an Evaporating Black Hole" on June 6th. In his talk, he elucidated the so-called information paradox of evaporating black holes and plainly presented his resolution of this long-standing paradox.
We are particularly pleased that we could invite Prof. Nomura not long after Coordinator Tada's own seminar at Berkeley. Frequent mutual visit between Berkeley and RIKEN would be most beneficial to iTHEMS, so we encourage all the iTHEMS members to find an opportunity to visit Berkeley, or invite somebody from there.

Quantum physics and science with open-source software: QuTiP, the Quantum Toolbox in Python

June 13 (Thu) at 10:00 - 11:30, 2019

Nathan Shammah (Postdoctoral Researcher, Theoretical Quantum Physics Laboratory, RIKEN Cluster for Pioneering Research (CPR))

I will address the rise of open source software based on the Python language ecosystem in quantum physics research, in particular with relevance to quantum technology and quantum computing. I will introduce the Quantum Toolbox in Python, QuTiP, a very popular software in the quantum tech community, whose core development has revolved around Prof. F. Nori’s group at RIKEN since 2011. QuTiP is open-source software for simulating the dynamics of closed and open quantum systems, and is used for quantum information science and cavity quantum electrodynamics studies. The QuTiP ecosystem has grown considerably in the past years, with many quantum tech libraries using its functionalities, similarly to what has happened for AstroPy in the astrophysics community.
Following the seminar, an interactive session will illustrate some features of this software package library. I will also show, drawing from recent research examples, how everyone can build its own library. Only a laptop with wifi working is required to join the hands-on session.

g-RIPS Sendai 2019

June 17 (Mon) - August 9 (Fri), 2019

GRIPS (Graduate-level Research in Industrial Projects for Students)-Sendai program was held last summer (June 18 - Aug. 10, 2018) with the support of iTHEMS as well as other institutions and companies. Two industrial projects were launched under the suggestion of TOYOTA and NEC, and two teams composed of US and Japanese students have worked intensively to find solutions of these problems. See for the details of the GRIPS program and the summary of activities at GRIPS-Sendai 2018.

This year, GRIPS-Sendai program will be held from June 17 through Aug. 9, 2019 with a larger scale under the support of iTHEMS. Stay tuned for further information.

Colloquium

iTHEMS Colloquium

Spacetime Geometry of Black Holes, Wormholes, and Time Machines

July 2 (Tue) at 15:30 - 17:00, 2019

Pei-Ming Ho (Distinguished Professor, Department of Physics, National Taiwan University, Taiwan)

Since the advent of General Relativity, people have found many solutions with interesting spacetime geometries. Most notably, the black holes have attracted a lot of attention for their roles in generating gravitational waves, and for inducing the information loss paradox. In this talk, we consider black holes amongst other geometric structures and investigate the subtlety involved in the quantum effect such as Hawking radiation. In this context, we mention wormholes and time machines, and explain how they are conceptually related to the geometry under the horizon of a black hole. There will also be comments on my recent research result about how quantum effect must be large for observers sitting on top of the black hole horizon.

Workshop

SOKENDAI-iTHEMS Joint Workshop "Genetics meets Mathematics"

July 7 (Sun) - 8 (Mon), 2019

Jeffrey Fawcett (Senior Research Scientist, iTHEMS)

7月7,8日に総研大葉山キャンパス近くの研修施設レクトーレ葉山にて遺伝・進化の研究者と数学・物理の研究者の交流を深めることを目的としたインフォーマルなワークショップを開催します。

生物の知識が全くない(主に数学・物理の)研究者を対象とした、生命の分子レベルでの多様性を説明しうる集団遺伝や分子進化の理論などに関するレクチャーを行います。また、今後の相互作用の可能性がありそうなテーマに取り組む数学・物理の研究者にも講演していただきます。

参加費・宿泊費は無料(懇親会費を頂く場合があります)で、前日の7/6と7/7に会場の宿泊施設に泊まることが可能です。プログラムの詳細は今後変更する場合があります。

登録締切:6/24
