Welcome to Akarsh Simha's homepage.

NOTE: This site is occasionally updated and the information here might be outdated.

I'm currently a graduate student in the Physics Department of the University of Texas at Austin. I am co-advised by Prof. Phil Morrison and Prof. Mark Raizen.



My research lies primarily in experimental observations of and development of theories pertaining to Brownian motion.

I have worked with experiments on measuring Brownian Motion with the Raizen Group. Our experiment successfully measured the hydrodynamic instantaneous velocity (calculated using an effective mass) of a microsphere suspended in acetone executing Brownian motion. The results were published in Science in early 2014. Thereafter, we made improvements to our set up so that we could acquire a large number of trajectories of the same particle, in order to amass enough statistics to test the Maxwell Boltzmann distribution in the tails. Our results were published in Optics Express in early 2015. I continue to collaborate with the Raizen group on experiments related to Brownian motion.

On the theoretical side, I am broadly interested in mathematical physics, and I am working on formalizing and improving existing hydrodynamic theories of Brownian motion can be improved.

Linux and Open Source Software

I'm a user of and contributor to Free and Open Source Software. I contribute to KStars, which I use to satisfy my astronomy computing needs. I also maintained KStars for a brief period of a year when I had more time on my hands as an undergraduate. KStars is part of the KDE project.

I also wrote the code and most of the textual material for the Logbook project, which uses KStars' DBus interfaces and other FOSS / Linux tools to generate astronomy logbooks.

I have also developed a better interface to the Digitized Sky Survey that is conducive for use by amateur astronomers, and it can be found here.

I use ArchLinux and Debian on my computers. My favourite editor is Emacs. I use irssi for my IRC client. I love GNU Screen. My favorite programming language is C++. I really love the new features of C++1x.

Some of my other small projects are available on my Github profile.
