Di-Omega in QCD on the front page of an in-house magazine

2018-12-13

Di-Omega in QCD reported in the previous iTHEMS NewsLetter became a front page of the latest news letter of "Science and technology companies pension fund".
It is amazing that the pension fund organization is interested in elementary particle physics!

Snapshot of a Discussion

2018-12-13

iTHEMS members have discussions not only on natural science and mathematical science but also on social science and history. Here is a snapshot of a discussion on ancient history of China by Yongjia Huang and Hiro Nagataki at our common room 246-248 on Nov.30, 2018.

Hot Topic

The RIKEN-NTU Workshop on Recent Developments of Chiral Matter and Topology

2018-12-13

The RIKEN-NTU Workshop on Recent Developments of Chiral Matter and Topology was held at Centre for Theoretical Physics in National Taiwan Univ. (NTU). on Dec.6-9, 2018.

There were about 80 participants both from particle/nuclear physics and condensed matter physics from Japan, Taiwan, China, and US. There were about 30 scientific talks with very stimulating discussions on chirality and topology from low-energies to high-energies. From RIKEN, A. Furusaki (CPR/CEMS), Y. Hidaka (RNC/iTHEMS), M. Hongo (iTHEMS), N. Nagaosa (CEMS), T. Ozawa (iTHEMS) and T. Hatsuda (iTHEMS) gave talks. The workshop was held in the new building "NTU Cosmology Hall" which was just completed at the north end of the NTU campus in Taipei.

Math Lecture

Theory of Operator Algebras

Theory of Operator Algebras (6th)

December 20 at 15:30 - 17:00, 2018

Dr. Yosuke Kubota (Research Scientist, iTHEMS)

Title: An introduction to operator algebras

Abstract: Operators are linear maps from a (usually an infinite dimensional) linear space (most frequently the Hilbert space) to itself, which is like matrices of infinite degree. Operators form an algebra by obvious addition and multiplication. Operators appear in most of the fields in mathematics, in algebra, in geometry, in analysis, ... Some of the key words at the beginning of these lectures are "spectral theory" "operator algebras" "Tomita-Takesaki theory". These lectures are for non-professional people.

Venue: Seminar Room #160, 1F Main Research Building, RIKEN

Event Official Language: Japanese

Lecture

Universal clusters and Efimov physics

January 8 at 10:30 - 17:00, 2019

Dr. Pascal Naidon (RIKEN Nishina Center)

Unlike classical systems, quantum few-body systems can be unbound in the presence of short-range attractive forces. Near the critical strength of the forces at which they can become bound (resonant forces), they exhibit universal properties that are independent of the details of the forces. In this lecture, I will explain in detail the universality of systems with resonant short-range forces, in particular the Efimov effect for 3 or more particles. I will also present the universal properties of systems with power-law interaction forces, such as van der Waals forces that are relevant to neutral atoms.

Co-hosted by iTHEMS

The 7th International Symposium on Data Assimilation (ISDA2019)

January 21 - 24, 2019

The symposium will focus on the cross-cutting issues shared in broad applications of data assimilation from geoscience to various physical and biological sciences. In particular, the symposium will enhance discussions among researchers with various background on, for example, non-Gaussian and nonlinear data assimilation problems, Big Data Assimilation (BDA), high-performance computation (HPC), Uncertainty Quantification (UQ), advanced intelligence (AI) and machine learning, multi-scale and multi-component treatments, observational issues, and mathematical problems.

Abstract Submission Deadline: October 14, 2018 at 11:59 p.m. UTC
