拠点研究員のプロフィール

2014年10月にCMSIに着任した拠点研究員を紹介します。

 

Bhattacharyya

Swastibarata Bhattacharyya

Materials Science Division Researcher

Department of Physics,
Yokohama National University


I did my masters in physics from Indian
Institute of Technology Guwahati. 
I received my PhD in the field  of material science
from Indian Institute of Science,Bangalore. 
At present, I am working on first principles
mapping onto phase field model at Department of Physics, 
Yokohama National University, Japan

Motivation for applying for the position

To learn development of first principles based theory and code that will be used to study materials properties.

Mission/Role

Phase field methods are very effective in studying the evolution of microstructures in various materials.
We want to bridge this empirical method to the first principles based atomistic methods.

Ambition

To learn and contribute to the first-principles allelectron mixed basis program TOMBO.

Sankar Kumar Deb Nath

Sankar Kumar

Deb Nath

Materials Science Division Researcher

Institute for Materials Research, 
Tohoku University

 

I obtained Ph.D. from the department  of Mechanical Engineering, Bangladesh
Universityof Engineering and Technology, 
Dhaka, Bangladesh on the mechanics of composit materials.Majored in multi-scale 
modelling in mechanics of solids and liquids, atomistic simulations of physics
and chemistry related problems. 
Currently I am working on the phase 
field modelling of Cu, Al and Cu-Al alloys using molecular dynamics simulation.

Motivation for applying for the position

Dendrite structures are formed during the solidification of pureand alloy  materials due to the anisotropy of the phase change of the solid-liquid interface. 
Detailed investigation of the physical and thermodynamic properties of the solid
liquid
interface are needed by the atomistic approach like molecular dynamic
simulations to study the anisotropy
of the solid-liquid  interface during solidification using the large scale phase field modelling.

 

Mission/Role

The anisotropy of the solid-liquid interfacial properties of
Cu, Al and Cu-Al alloys such as kinetic
coefficient, melting point,
interfacial free energy
etc. will be determined from the project.

Ambition

My aim is to investigate the thermodynamic properties of the solid-liquid interface of Cu, Al and Cu-Al alloys.

Ruiz-Barragan

Molecular Science

Division Researcher

Japan Atomic Energy Agency

 

Graduated in Chemistry
at
University of Girona and 
received the Doctorate in the same university
with a
exited states and non-stationary 
processes thesis. Current research with
path
integrals and QM/MM Molecular
dynamics in
Shiga's group at JAEA .

Motivation for applying for the position

Develop new methods for studying dynamics. Chemist is not a static
science and I think that we need to understand correctly the movement of
atoms and molecules to improve the reaction and obtain greener ways
to produce some products.

Mission/Role

To improve the path integral code for QM/MM and use it for study some
reactions with the
solvent for understand the temperature and the isotope
effects in reactions.

Ambition

Provide a new program for doing molecular dynamics and path integrals at the same time that I improve my conception of the molecular movement.
