We develop custom tools based on our analytical and computational solutions to the
problems. Our custom solvers for emitter-matter interactions are based on volume
integral approaches in frequency domain like Discrete Dipole Approximations (DDA).
We have other resources developed that are useful in iterative methods for solving
high-condition / large linear systems. We make our general purpose tools available
freely to others wherever possible.
Multi-core processors with large RAMs are used for simulation of optical processes.
In addition, the computational resources of SERC and its cluster computing facilities
are available freely.
Though the group is primarily involved in theoretical studies and computational models,
we also contribute to experiments in developing materials and sensors. Some of it
may involve designing and setting up devices / experiments, and in cases explaining
new data and optical phenomena observed in experiments. These are done in collaboration
with the relevant labs in departments of Nanoscience (1,2) and Physics (1).
Science is built up with facts, as a house is with stones. But a collection of facts
is no more a science than a heap of stones is a house.
