Brief Description of Research Interest :

My research at CeNO spans a broad area of theoretical and computational Physics with a major emphasis on Nano-optics, Nanoplasmonic and Ultrafast phenomena in light-matter interactions. In my Ph.D. dissertation entitled “Ultrafast Laser-induced Kinetics in Two-dimensional Materials,” I theorize the fundamentals of an ultrafast and ultrastrong optical field interacting with graphene and graphene-like nanocrystals as a prototype of the two-dimensional class of materials. I have studied a new class of phenomena in condensed matter optics when a strong optical pulse field 1-3 V/Å reversibly changes the solid within an optical cycle. During a single oscillation of a strong optical pulse, a dielectric crystal undergoes a reversible transition to a semi-metallic state. Such a pulse drives ampere-scale currents in dielectrics and controls their properties in a non-perturbative manner on a 100-as temporal scale. I have also theoretically investigated the dynamics of graphene, a semi-metal, under a strong ultrashort pulse field revealing unique behavior inherent in graphene. These are fastest phenomena in optics unfolding within half period of light. Our findings hold application in spectroscopy, imaging, laser technology, transmitting and processing information with speed and accuracy far beyond the capabilities of conventional optics and electronics.
