Japan-Switzerland Joint Workshop: New Trends in Theory of Correlated Materials, September 8-10, 2010, Chiba, Japan


Scope and Background

This Japan-Switzerland Joint Workshop is a sequel to the previous one, "New Developments in Strongly Correlated Electron Systems" held at ETH in Zürich, Sep. 18-21, 2009.

The scope of the conference focuses on emerging new topics in strongly correlated many-body systems including

  • exotic quantum phases
  • novel superconductors
  • quantum phase transitions
  • topological phases
  • non-equilibrium properties
  • entangled quantum dynamics
  • new computational approaches
  • ...


This workshop is supported by "Emergence of Heavy Electrons and Their Ordering", Grant-in-Aid for Scientific Research on Innovative Areas, The Ministry of Education, Culture, Sports, Science and Technology, Japan.

  • Kazuo Ueda (ISSP, Kashiwa)
  • Hiroaki Kusunose (Ehime Univ.)
  • Synge Todo (Univ. of Tokyo)
  • Manfred Sigrist (ETH, Zürich)


As a conference site we chose a nice resort facility, "Seimei-no-mori Resort", built in a site of total area 3,300,000 square meters to spread through Chiba, Boso. They offer the largest scale of composition accommodations in Chiba, including lodging, a restaurant, various sporting facilities, swimming pools and conference rooms.
