Arjun Varma R.

Hello there. Welcome to my homepage!

I am a PhD candidate, working at the department of Metallurgical Engineering and Materials Science at IIT Bombay, with Prof. M P Gururajan and Prof. Prita Pant.

My PhD thesis focuses on the study of the effect of dislocations on phase transformation phenomena using phase field simulations. Essentially, we study the effect of elastic interaction between dislocations and the solutes in a two-phase system leading to interesting phase transformation phenomena.

We have also used the phase field dislocation dynamics (PFDD) code developed to look at the equilibrium stacking fault widths in different face-centered cubic alloy systems. The generalised stacking fault energy is incorporated from atomistic or density functional theory calculations performed by our collaborators at Prof. Vaishali Shah’s group in University of Pune. In addition, during the early years of my PhD, I was also part of an ab-initio study of the effect of electron-phonon interactions on the total energy and hence, the stability of different semiconductor polymorphs.

As part of an Overseas visiting doctoral fellowship (SERB-OVDF 2019), I have also spent six months at GPM2-SIMaP, Universite Grenoble Alpes with Prof. Marc Fivel’s research group. During this fellowship, I worked on an in-house discrete dislocation dynamics simulation package called NUMODIS, trying to develop an algorithm to model slip transfer.

Here, you will find details about my projects, links to publications, blog entries and a brief CV. Thanks for visiting!
