Position Description:    

*** the listing date or deadline for this position has passed and new applications are no longer accepted. ***

We offer two post-doc positions in the area of theoretical quantum condensed matter with a focus on spin and topological phenomena in semiconducting and magnetic nanostructures, in the Quantum System Theory Research Team in RIKEN Center for Emergent Matter Science (Tokyo) lead by Prof. Dr. Daniel Loss.

Research Field

Our team works on the quantum theory of condensed matter with a focus on spin and topological phenomena in semiconducting and magnetic nanostructures. In particular, we investigate novel mechanisms and seek new platforms hosting topological or spin phases in solid-state systems, including helical spin texture, topological insulators and topological superconductors, which have potential hosting topological quantum states, such as Majorana fermions and parafermions. Moreover, we also investigate (quasi-)one-dimensional Tomonaga-Luttinger liquid, nuclear spins in semiconductors, many-body effects in low-dimensional systems, (fractional) quantum Hall effect, strongly correlated electron systems, spin-orbit interaction, and quantum transport phenomena.

Job title, available positions

Research Scientist or Postdoctoral Researcher: 2 positions
Postdoctoral Researcher is defined as those who obtained a doctoral degree within the last 5 years.
Research Scientist is defined as those who obtained a doctoral degree more than 5 years ago.

Job judgement will be decided based on applicant's ability, aptitude etc.

Job Description

The post-doc will join ongoing activities on spin and phase coherent phenomena in semiconducting and magnetic nanostructures, as well as quantum information processing in the solid state. Topics of current interest include: many-body effects in low-dimensional electronic systems, nuclear magnetism, quantum transport of magnetization, topological quantum matter, topological superconductivity, topological insulators, Majorana fermions and parafermions, decoherence phenomena in semiconductors, hybrid systems, Floquet systems, optical effects, etc. 

The stimulating environment of the established RIKEN Center for Emergent Matter Science offers many opportunities of interactions with experimental and theoretical groups with related interests. The new Postdoctoral Researcher could also benefit from collaborations with theoretical groups at the University of Basel, Switzerland. 

Qualification Requirements

Applicants must have a Ph.D. in theoretical Condensed Matter Physics (or expect to receive a doctoral degree before the start of employment).
They must be able to read, write, and speak fluently in English. 

Work location

RIKEN Wako (2-1 Hirosawa, Wako, Saitama 351-0198)

Salary and Benefits

  • 1.A one-year fixed-term employment contract, renewable based on evaluation, to a maximum 10 years (Research Scientist) or 5 years (Postdoctoral Researcher) of employment.
  • 2.RIKEN may adjust the above maximum period of renewability based on a) the employee’s abilities, work load at the time of contract completion, performance and work attitude and b) the continuation of the employee’s center, laboratory or project and RIKEN’s management situation and budget at the time. In principle, employment contracts will not be renewed for individuals older than 65 years.
  • 3.The employee’s period of fixed-term employment cannot exceed 10 years from the initial date of hire (or 10 years from April 1, 2013 for fixed-term employees already at RIKEN prior to this date).
  • 4.When the center to which the Employee is affiliated is scheduled for a final review in FY2024 and it is decided that the Employee's research will not be continued, the provision given above for projects of limited duration applies and the Employee's contract will not be renewed for the FY2025 year that would extend employment beyond the center's final fiscal year.
  • 5.When the Employee's research is scheduled for review in the Employee's 5 years from the original date of hire at CEMS, and when it is concluded that there is reason* to believe it will be difficult for the research (or technology development) to be continued, the employment contract will not be renewed for the next year. (*The reason may relate to the Employee's abilities, performance and/or work attitude.)

In principle, the first two months of employment is considered a trial period.
Salary will be commensurate with qualifications and experience. Commuting and housing allowances will be provided. Social insurance will be applied. 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.
RIKEN has introduced telework as a temporary and special measure to prevent the spread of COVID-19. You may be asked to work from home according to the instructions of the institute. You can also choose to work from home with the permission of your supervisor.
No smoking on site (designated smoking areas available).
These and other provisions are in accordance with RIKEN regulations.

RIKEN is promoting a Gender Equality Program by taking various measures to create a workplace where both men and women are able to give full rein to their talents and abilities. When applicants are judged to be equally qualified on the basis of fair and impartial criteria, women applicants will be given preference.

Also, eligible for an exemption from repayment for category 1 scholarship loans provided by the Japan Student Services Organization before fiscal year 2003, and eligible applying for the MEXT Grants-in-Aid for Scientific Research (Kakenhi).
