what we do

We are a computational group in the Chemistry Department at IIT Guwahati. Our major research interests focus on the quantum dynamical studies of various chemical reactions. The time-dependent Schrodinger equation is solved to study the gas phase atom-molecule and molecule-molecule collision processes and vibrational spectra of different systems. We are also interested in studying different chemical control schemes using chirped laser pulses. The fact that we can selectively excite a particular mode and then control the outcome of the dynamics is of fundamental importance for a variety of processes such as population flow in atomic systems, branching ratio in chemical reactions and in biological systems. Use of a combination of theoretical calculations and movies of wave packets gives rise to an understanding of the mechanism of the processes. For carrying out all these dynamical studies an accurate representation of the forces is needed. Either an accurate potential energy surface is computed by carrying out extensive computational calculations or an on-the-fly dynamical calculation is performed.

about

Dr Aditya Panda joined the department as an Assistant Professor in June 2007. He got his BSc degree from Ravenshaw college, Cuttack and MSc degree from Utkal University, Bhubaneswar. He joined Prof. Sathyamurthy's group in IIT Kanpur as a PhD scholar in 1999. After finishing his PhD in 2004, he went to UK to carry out postdoc works in Nottingham and Cambridge with a Royal Society Fellowship. In April 2006, He moved to the University of Heidelberg in Germany as Alexander von Humboldt Fellow.
