Surajit Sen (born November 28, 1960, in Calcutta (modern name Kolkata) in India) is a physicist who works on theoretical and computational problems in non-equilibrium statistical physics and in nonlinear dynamics of many body systems.
[2] Sen is credited with developing an exact solution for the Heisenberg equation of motion in a quantum mechanical many body system in 1991.
[23] Sen was elected as a Fellow[24] of the American Physical Society[25] in 2008,[26] for the discovery of how solitary waves break and secondary solitary waves form in granular media, for his leadership in organizing forums to represent and recognize the physicists from India and for raising consciousness about the problems and the importance of rural science education in India and the developing world.
He was also elected as a Fellow of the American Association for the Advancement of Science in 2012[27] for pioneering research on solitary waves and their collisions in granular media and for sustained outstanding service and leadership in international physics.
More recently, Sen served as a Distinguished Visiting Professor of Biosciences and Bioengineering at the Indian Institute of Technology Jodhpur, India, where one of his focus areas have been desert ecosystems.
