Summary
Arko Pratim Sen is interested in research focusing on the fundamental attributes of nature. His Ph.D. dissertation was a theoretical physics research to search for exotic low-mass scalar fields from merger of a binary neutron star. This was carried out by analyzing the data from the atomic clocks on board the GPS satellites. Through this work a statistical confidence limit was set on the exotic field interaction energy scale which surpass previous astrophysical bounds by several orders of magnitude, thus tightening the parameter space available for models of ultralight exotic scalar fields.
In the newly joined research group for his postdoctoral job, Arko studies molecular dynamics and related phenomena based on photoionization of different molecules. The COLd Target Recoil Ion Momentum Spectroscopy (COLTRIMS) is one of the experimental techniques that helps to investigate multiple-particle dynamics associated with photoionization. Arko aims to work on data from several such experiments to expand scientific knowledge in this field.
