Our group work in the areas of theory and computational aspects of condensed matter systems with theoretical and computational tools. The main focus of research includes, the theory of light-matter interaction at nanoscale, modeling of nano-photonic systems, electronic structure calculations and atmospheric science. Basic Physics and potential applications are explored using state of art computational and mathematical tools, for example, density functional calculations using VASP, finite element method(COMSOL), FDTD(MEEP) are used. We have developed computational tools to investigate problems arising from condensed matter systems relevant to Nano-Optics, Low-Dimensional Structures etc. Vienna Ab initio Simulation Package(VASP) uses density functional theory as the fundamental framework for ab initio calculations, geometry optimization, electronic band structure and material property calculation. There are also works going on in the field of atmospheric science such as the influence of moist-convection on the dispersion characteristics of complex equatorial waves. We have developed theoretical framework to address the dispersion and multi-scale interaction of convectively driven moisture modes within the equatorial waveguide. The students are trained in machine learning and various statistical models.
