WELCOME to V.K. Jindal’s Home Page Uptil
recent past,
we have devoted significant effort on understanding harmonic and anharmonic
effects in simple, molecular and complex solids. Codes were developed in
early eighties to compute phonon line widths and shifts in molecular
crystals. Experiments using inelastic neutron scattering were also carried
out to measure the temperature dependence of phonon profiles and correlating
these with theoretical models for organic molecular crystals. Study of
micellar systems using Small Angle Neutron Scattering Experiments leading to
shear induced organization and decay of rod-like mi-cells was carried out. Since
recently,
we have been involved in areas of research, like modelling structure and
dynamics of doped and undoped carbon cluster solids, fullerene solids, carbon
nanotubes and nanoparticales, simple and organic molecular crystals. We also
study anharmonic effects, and energy flow in materials under high static and
dynamic pressure. Experimental activities involve irradiation of thin film
samples to heavy and swift ions and characterizing them looking for phase
transformations, effect of fluence and ion mass and charge, and modification
of chemical bonding. We also work on methods to produce carbon nanotubes. Fullerene Solids and Nanotubes: Using theoretical model
potentials, we study bulk, structure and thermodynamic properties of
materials of carbon nanotubes and fullerenes. This has also helped in
studying phase transformations under high pressure and temperature in these
materials. Also structure of single wall nantubes has been studied in detail
under hydrostatic pressure. Very
recently,
we started to investigate hetero-fullerenes, polynitrogen clusters inside
fullerene cage and graphene with boron and nitrogen doping, and use abinitio
calculations to study electronic, structural and vibrational
properties. We also calculate structure and magnetic properties of
semiconducting Ge, ZnO and fullerne nano clusters. For
