Summary


Broad Area of Research: Chemical Physics, Computational Condensed Matter Physics, Theoretical Chemistry, and Chemical Physics.

Research Overview: Understanding the physics of strongly correlated systems using numerical techniques, such as Exact Diagonalization and Density Matrix Renormalization Group (DMRG). Strongly correlated materials are characterized by strong electron-electron interactions by virtue of which these systems show various novel and exotic electronic and magnetic phenomena. 

Current Research: Unconventional superconductivity in multi-band carbon-based materials, theory of primary photo-excitations in low-band gap donor-acceptor copolymers, cooperative charge-orbital ordering in spinels.

Past Research: Ultra-fast dynamics of spin-charge separation and transport in low dimensional conjugated polymeric systems, typified by trans-polyacetylene.

 Future Research: Physics of multi-orbital 2D systems, dynamics of quantum quenches, organic spintronics, Quantum Monte Carlo methods, matrix product and tensor network states.
