Our research centers on theoretical condensed matter, computational physics, quantum condensed matter, computational materials science, and renewable energy materials, with particular emphasis on discovery and understanding of complex and correlated organic and inorganic phases and their interfaces; electronic excited states, including quasiparticle and optical excitations; weak (non-covalent) interactions; and low-dimensional transport behavior.
For much of our work, we draw upon contemporary “first-principles” density functional theory (DFT)-based approaches. First-principles approaches are theoretical methods at the nexus of condensed matter physics, quantum chemistry, and computational materials with the ability to predict measurable properties of materials with good accuracy without adjustable empirical parameters, i.e. through approximate solutions of the quantum mechanics of a system of interacting electrons in a field of nuclei.
Our research is often multidisciplinary, focuses on both hard and soft matter, and reflects a breadth consistent with the flexibility of first-principles DFT-based methods. Importantly, we interact closely with experimental research groups to guide and be inspired by state-of-the-art studies of real physical systems, and to validate and further develop our understanding of materials.
Our long-term efforts include the development of electronic structure methods to treat increasingly complex materials and study time-dependent phenomena. We mainly work on (i) Condensed Matter Science and Material Physics, (ii) Method Development , and (iii) Applications in Energy Applications and Nanoscience.
Another currently exciting area is understanding how correlated quantum states transport charge, spin, and heat: aside from fundamental interest, this can lead to new devices for spin-based electronics and quantum sensing. We also use concepts from quantum information theory to analyze problems in condensed matter physics. Theoretical work on these problems benefits from an increasing quantity and quality of experimental data, and students in the group are encouraged to interact with experimental efforts at IIT Indore and elsewhere.
