New iTHES site is ready to launch
We have been working on iTHES website for renewal and it is now ready to launch. You can check it out by yourself at
http://ithes.riken.jp/test
We will start using the new site shortly but in the mean time we would appreciate your input on the new site.

iTHES Seminar
"The kernel polynomial method and its applications"
Prof. Alexander Weisse (Max Planck Institute for Mathematics, Bonn, Germany)
Date: Dec. 15, 2014, 11:00 - 12:00
Place: Main research building, 224 & 226
Abstract: Efficient and stable algorithms for the calculation of spectral quantities and correlation functions are some of the key tools in computational condensed-matter physics. I will give a short review of algorithms based on Chebyshev expansion and of the kernel polynomial method, which usually scale linearly with the problem dimension. The capacity of these methods will be illustrated with examples from the fields of disordered systems (densities of states, conductivities), electron-phonon systems, or quantum spin models (finite-temperature correlations). In addition, I will show how the kernel polynomial method can be embedded into other numerical techniques, e.g., Monte Carlo simulations.


 

Person of the Week

I am very excited to have joined iTHES as an associate member of the MCC team. Born and raised in Hong Kong, I obtained my BSc from the Hong Kong University of Science and Technology at the scenic Clearwater Bay in Kowloon, and then a PhD in 2011 from Stanford University near San Francisco. After spending a couple of happy years at Kyoto University and RIKEN, I am now working at ISAS as a JAXA International Top Young Fellow.

I am interested in the high-energy phenomena associated with particle accelerators in our Universe, and how we can use them to decipher the origin of cosmic rays. It has been more than 100 years since the first experimental proof of the extraterrestrial origin of cosmic rays, but their exact origin still remains one of the biggest unresolved mysteries to mankind. To solve this puzzle, I spend most of my time at work pondering about the physics and astrophysics of the intriguing ‘cosmic accelerators’, with particular attentions paid to objects with strong shockwaves such as those found at the young and middle-aged remnants of supernovae. Together with my collaborators, I am developing a growing simulation code that self-consistently calculates the acceleration of cosmic ray at various astrophysical shocks, and the accompanying electromagnetic radiation and neutrino signals. The code has been applied successfully to confront multi-wavelength observations of supernova remnants, and to provide robust predictions for future observations by new space and ground-based telescopes. I also have a background in observational gamma-ray astronomy being a collaboration member of the Fermi Gamma-ray Space Telescope since 2006, and more recently a member of the Cherenkov Telescope Array which is a next-generation ground-based observatory designed to observe our Universe at very high energies using the atmospheric Cherenkov light produced by the cosmic gamma-rays.

I am hoping that my participation will further enrich and diversify the research activities at iTHES to help fulfill its ambitious goals.
