The Central Research Facility (CRF) forms an integral part of research activities in the physical sciences and biosciences programmes of the college. It is being upgraded every year in terms of procurement of new advanced level instruments and computational facilities and the total assets now amount to more than Rs.2.0 cr. The centre now plans to extend its infrastructure to other Colleges and Institutions.

HP Proliant Server:
- A new reaction path determination method is developed to determine the lowest lying saddle point on a general path connecting the reactant and the product. The search is set up as an optimization problem and solved using the Adaptive Mutation Random Hill Climbing method.
- Using the real value coded Genetic Algorithm coupled with the nwchem quantum chemistry package for energy determination, we are trying to determine the global minimum structures of small sized (10-20) -doubly charged- water clusters.
- Measured the effect of gravitational wave on merging binary system near binary black hole.
- Designed a dynamical model of cosmology based on some recent research works and trying to test the model using standard data.
- Inclusion of effects of rotation in QMD model of quark.
- Studying effect of gravitational waves near strong gravitational lenses.
- We are studying the formation mechanism of Kirkwood gaps in the main asteroid belt in our solar system. First we were trying to understand this in the context of planar circular three body problem. Then we realized that planar elliptical three body problem is more appropriate for this. So, we were simulating directly the equations of motions of Sun-Jupiter and an asteroid (which initially placed at a particular gap). Initially we missed out several parameters of the problem which we have presently sorted out and able to produce similar results like previous authors using a new N-body code.
- Two students use the desk for theoretical work along with the internet facility. One student works on gravitational collapse and the other student works on cosmological solutions in modified theories of gravity.
