Professor Anirban Chakraborti joined the Centre for Complex Systems Studies, SC & IS, Jawaharlal Nehru University, in 2014 and established this laboratory. In the group there are physicists, computer scientists and mathematicians working in various areas: Econophysics, Sociophysics, Statistical Physics, Nanomaterial Science, EEG analyses and pattern recognition, Big Data analytics, etc.
Studies consist of conceptual approaches of socio-economic problems using methods of statistical physics. Prof. Anirban holds the distinction of being the first Ph.D in Econophysics from India. Some of the areas the lab has contributed are:

A study of multiple unique interacting components and their adaptation to changing environment. Some of the areas of interest are :
The lab has made significant analysis of stock market data, both low frequency(daily) and high-frequency (intraday tick-by-tick). The prominent areas of interest are :
The research on statistical physics focuses not only to its application to problems in economic systems (Econophysics) but also to combinatorial optimization such as the Traveling Salesman problem, extreme value statistics and study of “complex systems”.

Our experimental study focuses on exploring the photophysical properties of nanomaterials, interaction of biomolecules with two dimensional nanosheets, sensing and imaging using nanomaterials. Different spectroscopy tools are used to investigate optical properties of the nanomaterials. Fluorescence spectroscopy is used for fluorescence resonance energy transfer (FRET) in nanomaterials. Raman spectroscopy technique is used for sensing of foreign molecules and the sensing is based on surface enhanced Raman scattering (SERS) by plasmonic nanoparticles.
