[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.
