Research Field

The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international hub for computational science that promotes “science of computing, by computing, and for computing.” R-CSS positions the technology in which RIKEN has strengths (R-CCS technology) and the software developed by RIKEN that contributes to science, technology, industry, and society (R-CCS software) as its “core competence in computational science driving science as a whole.” R-CCS aims to develop these technologies, disseminate them domestically and internationally, and produce results. In addition, R-CCS is utilizing its expertise to operate the supercomputer “Fugaku” which was developed as a national project in accordance with Japanese laws and regulations.

One of our main focuses is to develop state-of-the-art numerical methods for simulating ground states as well as quantum dynamics of strongly correlated quantum systems. In addition, we are exploring new computing paradigms as a grand challenge for information science. In particular, we are engaged in research and development of quantum computing for simulating quantum many-body systems, and of quantum computational simulations using classical computers.

Job title and Job description

Job title

Research Scientists or Postdoctoral Researchers: a few positions

Job description

In accordance with the research project of COI-NEXT "Co-creation of quantum software and HPC/simulation technologies for sustainable AI" (PI: Shinji Todo (The University of Tokyo), Research period: October 2022 - March 2032), research and development of the subproject " Development of quantum simulation methods for many-body problems in materials science (quantum simulation)" or the subproject "Quantum-classical fusion algorithms based on quantum embedding (quantum embedding)" is carried out in cooperation with other project members. For example, it is expected to develop quantum algorithms for quantum many-body systems and demonstrate them using actual quantum computers, and to develop quantum information compression techniques based on tensor network formalism.

Qualification

Applicants must have a doctoral degree in a related field or expect to receive a doctoral degree before the date of appointment. In general, those who earned a doctorate within the past 5 years will be appointed as Postdoctoral Researcher, and those who earned a doctorate more than 5 years ago will be appointed as Research Scientist.

Candidates in the field of condensed matter physics, statistical physics, quantum chemistry, particle physics, nuclear physics, quantum information, or machine learning are all encouraged to apply.

In principle, the first two months of employment is considered a trial period.
Salary will be an annual salary based on experience, ability, and performance, and will consist of a base salary and a variable salary. The variable salary will be determined each fiscal year based on experience, ability, and performance. The monthly base salary is 295,100 JPY for Postdoctoral Researcher and 421,900 JPY for Research Scientist as of April 1, 2023. The monthly base salary and variable salary are subject to change due to amendments to RIKEN regulations.
Discretionary work, commuting and housing allowances will be provided. Social insurance will be applied.
The approximate amount of annual salary at the time of employment:
The monthly salary including discretionary work allowance at the time of employment for a candidate with 3 years of experience, ability, and achievement after completion of the doctoral course as Postdoctoral Researcher will be approximately 350,000 JPY and for a candidate with 7 years of experience, ability, and achievement after completion of the doctoral course as Research Scientist will be approximately 520,000 JPY.
Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai).
This position falls under the specialized duties discretionary work system; one working day will be calculated as 7 hours and 30 minutes.
Days off include public holidays, New Year's holidays (Dec. 29 - Jan 3), and RIKEN Foundation Day.
Paid leave includes annual paid leave (up to 20 days per year depending on the month of employment), special paid leave (childcare, family nursing care, etc.), and work-life balance holidays (up to 7 days per year depending on the month of employment).
