[Recruitment] Postdoctoral position at Saitama U. 
(Quantum chemistry and reaction dynamics) [deadline Feb. 12]

One postdoctoral position is available in the group of Toshiyuki 
Takayanagi at Department of Chemistry, Saitama University in Japan. 
The group focuses on quantum chemistry and reaction dynamics. A 
successful candidate is expected to carry out numerical calculations 
of potential energy surfaces and reaction dynamics of both gas-phase 
and grain-surface reactions relevant to astrochemistry in 
collaboration with the grant group described in the attached file. 
The candidates must have fundamental knowledge on quantum chemistry 
and interests in astrochemistry. The candidates with research 
experience in potential energy surface development are particularly 
welcome. The candidate should have finished his/her doctoral thesis 
before taking up the position. Japanese language skill is not 
required. The position is initially for one year with the annual 
extension depending on performance, up until March 31, 2025. 
Inquiries about the position can be made to Toshiyuki Takayanagi 
( tako@mail.saitama-u.ac.jp ). The position is open from April 1, 2021,
but the exact starting date is flexible.

Interested candidates should prepare the following documents in 
English or in Japanese, convert them to PDF (max 5 MB per email) and 
send them via e-mail to Toshiyuki Takayanagi 
( tako@mail.saitama-u.ac.jp ) with a subject line “Application for 
postdoc position’.
(1) Cover letter
(2) Curriculum vitae
(3) Publication list (Separate refereed papers from others. State 
your role for co-authored papers.)
(4) PDF of three relevant papers
(5) Statement describing your commitment and plans for the job
(6) Names and email addresses of two or more researchers who can 
provide reference letter upon request
(7) Your e-mail address and phone number

Please contact us if you do not receive a reply within two working 
days. The application deadline is February 12, 2021 (17:00, JST).

The fellow will receive a monthly salary of 350,000 JPY. Social 
insurance will be applied. Bonus and retirement allowances are not 
provided.

Next Generation Astrochemistry: Reconstruction of the Science Based 
on Fundamental Molecular Processes (FY2020-2024)

【Purpose of the Research Project】
Planet formation is a natural consequence of the star formation 
process, and there is an incredible variety of planetary systems, 
which are significantly different from the Solar System. Recent ALMA 
observations have revealed chemistry in planet-forming regions. 
Various complex organic molecules are found in protoplanetary-disk 
forming regions, and their abundances vary significantly among 
objects. This indicates that the Solar System may not have been 
common in terms of its initial chemistry, which invokes the 
discussion on the rarity of our existence. Progress of the Solar 
System exploration, including the recent successful return of the 
Hayabusa2 spacecraft, makes it possible to analyze pristine Solar 
System materials directly. The combination of such analysis with 
high-sensitivity observations of planet-forming regions will tell us 
the chemical origin of our Solar System and how common or rare it is 
in the universe. However, to tackle these questions, we have to 
revisit fundamental astrochemical processes. In the past decades, the
astrochemical studies focused on chemistry under extremely low 
temperature and density conditions, where only barrierless exothermic
reactions proceed efficiently. During the planetary system formation,
on the other hand, the physical condition changes dynamically 
resulting in dynamic interactions of molecules between gas and 
dust(ice) surface. Investigation of such physical and chemical 
processes is crucial to understand the formation of complex organic 
molecules and the chemical variety of planet-forming regions. This 
transformative research area aims at the re-establishment of 
“astrochemistry” by investigation of the microscopic chemical 
processes with the close collaboration of astronomy, planetary 
science, and molecular science, and also aims at understanding the 
origin of the Solar System from the view of chemistry.

【Content of the Research Project】
Following studies are planned in our research area.
1) High resolution/sensitivity observations and laboratory 
spectroscopy to explore the entire view of chemical evolution and 
its diversity.
2) Analysis of extraterrestrial organics, including the returned 
Ryugu samples, along with laboratory experiments to reproduce the 
Solar System organics.
3) Experimental study on gas-phase reactions based on advanced beam 
technologies. Reaction pathways and rate coefficients are 
investigated as a function of temperature.
4) Experimental study on dust surface reactions, which aims at the 
molecular-scale elucidation of the reaction elementary processes by 
the single-molecule surface spectroscopy.
5) Theoretical astrochemistry based on microscopic processes in the 
gas and solid phases. Construct the model of chemical evolution model
during the star and planet formation by the combination of 
hydrodynamic calculations, reaction parameters obtained by the 
laboratory experiments and quantum chemical calculations.

【Expected Research Achievements and Scientific Significance】
The next generation astrochemistry will reveal the chemical evolution
in the star/planet formation and the commonness/uniqueness of the 
origin of the Solar System. It is also applicable to various physical
conditions in space, i.e., the material evolution in the Universe in 
general, and enable us to use chemistry as a diagnostic tool for the 
structure formation. Our research area is also beneficial to various 
fields such as astrobiology, exoplanet research, material science, 
molecular chemistry, and surface science.

【Key Words】Astrochemistry:Chemistry taken place in space, which 
includes the Solar system and interstellar clouds.
