Seeking a Research scientist or Postdoctoral researcher (W20223)


Emergent Photodynamics Research Team
RIKEN Center for Emergent Matter Science
(Team Leader: Naoki Ogawa)

Research Field

The Center for Emergent Matter Science (Center Director: Dr. Yoshinori Tokura) is a strategic research center launched on April 1st, 2013. The center aims at constructing a novel condensed matter science and contributing fundamentally toward the realization of an environmentally benign, sustainable society which is recognized as a world-wide problem.

Emergent Photodynamics Research Team explores novel photodynamics of electron/magnon/phonon in condensed matter emerging via electron-correlation and strong spin-orbit interactions, by means of ultrafast imaging spectroscopy, THz, Brillouin/Raman, vis-IR, and magneto-optical spectroscopies.

Job title and Job description

Job title

Research scientist* or Postdoctoral researcher**

  • *Applicants who received doctoral degree 5 or more years ago
  • **Applicants who received doctoral degree within last 5 years

Job description

We expect highly motivated condensed-matter scientists with the background of optical spectroscopy. Successful candidates will carry out original research related to the electron/magnon/phonon dynamics in solids with various spectroscopic techniques. Intimate collaboration with team members is required.


Applicants must have a doctor degree (or are expected to have until the time of employment) in experimental condensed matter physics. Previous experiences in the field of optical spectroscopy on correlated electron systems and/or ultrafast optics is necessary.
