Since my undergraduate study, especially during the theses work, I have been involved in a research topic related to computational physics. For the first time I was introduced with numerical study using Monte Carlo technique to solve some differential equations governing phenomena of our nature. Since then, I am interested very much on computational aspects of physical properties.
Soon after the graduation on September 2009, I join the Group for Theoretical and Computational Physics,Research Center for Physics, Indonesia Institute of Sciences as a young scientist visitor. I worked on the modeling and performing numerical simulation for top-down nanomaterial processes using mechanical apparatus like ball mills. Through the project, I have learn a lot of things such as developing physical model, coding the program using Python, and performing numerical calculation using Monte Carlo on a parallel computer. Through my experience in several months working with Handoko`s group I felt comfort and enjoyed working on the topics of computational sciences.
In particular, so far we have dealt with a problem on simulating internal dynamics in a vial of ball mills. The model and simulation are intended to provide macroscopic descriptions of the internal motion without tracing the geometrical displacements of each matters inside the vial that is unobservable in real world. Using the Hamiltonian mechanics and statistical prescriptions, we have succeeded in relating the internal dynamics in terms of energy with the external system temperature. Since the relation is described as multi dimensional integral, the simulation has been performed using Monte Carlo technique.
I am so happy On 1st October 2010 I had chance for attending the Quantum Engineering Design short term program during one year in Japan. The program accepts exchange students from 7 Asian countries program.
The program aims to cultivate student who have passion in research. Students can conduct researches like computational material design for environment-friendly technology and can join academic conferences. Through that program, I could study related to first principles electronic structure calculation, involved in wider aspects of computational sciences especially its applications to the material sciences. I have learned much more things from basic theory to technical applications like the basic of density functional theory, technically for electronic calculation I love to use software Machikaneyama2000 and HiLapw. All of these open a new window for my view on doing research in theoretical and computational aspects of condensed matter physics.
