"Numerical Weather Prediction: Chaos, Predictability and Data Assimilation"
Dr. Takemasa Miyoshi (RIKEN AICS)
Place: 2F Large mtg.rm, Main Cafeteria (Bldg. C61)
Contemporary weather forecasting is based on numerical simulations with supercomputers, i.e., numerical weather prediction (NWP). The weather system is chaotic, and data assimilation plays a central role in predicting the chaotic weather by synchronizing a numerical simulation with the real world. Data assimilation integrates simulations (i.e., virtual world on computers) and real-world data based on statistical mathematics and dynamical systems theory, and brings synergy. Although data assimilation for large-scale computational problems has been evolving extensively in the field of NWP, data assimilation is a general approach potentially applied to a wide range of simulation studies. This lecture provides an introduction to NWP and data assimilation, and discusses the future perspectives of data assimilation research in the forthcoming “Big Data” and “Big Simulation” era.

"The Chiral Magnetic Effect: from Quark-gluon Plasma to Dirac Semimetals"
Prof. Dima Kharzeev (Stony Brook Univ. and Brookhaven Natonal Lab.)
Date: Sep. 24, 2015. 13:30-15:00
Place: Okochi Hall
Recently discovered 3D Dirac and Weyl semimetals possess massless chiral quasi-particles, and are affected by the triangle anomalies. Quantum anomalies can induce novel non-dissipative transport phenomena in these materials - so-called "chiral magnetic" and "chiral vortical" effects.
I will discuss the theory of anomalous transport, the experimental evidence from heavy ion collisions at RHIC and LHC, and the recent experimental observation of the chiral magnetic effect in Dirac semimetals.
iTHES Colloquium in November 2015
Date: Nov.10 (Tues) 15:00-16:30
Place: big conference room (2nd floor of the main cafeteria)
Speaker: Kazuyuki Aihara (Univ. Tokyo)
Fundamental Physics Using Atoms 2015
- Towards better understanding of our matter universe -
Nov. 30 (Mon.) -- Dec. 1 (Tue.), 2015
Oral sessions: RIKEN Wako, Okochi Hall (C32)
Poster sessions: Welfare and Conference Bldg. 2F (C61)
Recently much effort has been directed to investigation of the fundamental physics which exploits remarkable developments in atomic physics and/or quantum optics techniques. Examples include (A) test of the time reversal invariance by observing permanent electric dipole moments of atoms or molecules, (B) neutrino mass spectroscopy using atoms, (C) measurement of fine structure constant's time dependence with precession atomic clock etc. This conference aims to bring together recent research results, to discuss future prospects, and to expand research network, making this field more active and productive.
Person of the week
"Di-Lun Yang is a new foreign postdoctoral researcher in Quantum Hadron Physics Laboratory. His primary research interest focuses on applications of the AdS/CFT correspondence to the quark gluon plasma and relativistic heavy ion collisions. Recently, he has also been interested in finite-temperature field theory and kinetic theory pertinent to heavy ion physics."
