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
