My involvement in scientific research so far has remained confined largely to the area of theoretical vis a vis computational condensed matter physics in association with a few inelastic neutron scattering experiments. In my graduate days, I worked mainly on studying the lattice dynamics and phonon mediated pressure-induced structural phase transitions in lithium rare-earth (viz. Y, Yb) fluoroscheelites and also in various crystalline polymorphs of ZnCl2. I have recently studied the exchange coupling mechanism in Fe/Nb multilayers using the density functional theory(DFT). Currently, I am involved in developing a dynamical mean field theory(DMFT) based code that can be coupled with DFT results in order to study the correlation effects in solids.
Following are the areas of my major research interest:
Equilibrium thermodynamic properties of solids at high-pressure
Pressure induced structural phase transitions
Inelastic neutron scattering study of phonons and magnons
Exchange coupling mechanism in transition metal multilayers
Optic & dielectric properties of molten and glassy phases
Magnetic phase transitions and response functions in finite systems
Effect of correlation on phase transformations under pressure and temperature
