Computational nano-optics: Parallel simulations and beyond

Several researches undertaken in the plasmonics and nano-polaritonics are presented. Researchers have shown, both theoretically and experimentally, that the proper utilization of optical properties of metal nano structures at the subwavelength scale may lead to single atom/molecule optical trapping. They have recently showed that the local electromagnetic (EM) fields associated with metal nanoparticle dimmers are noticeably dependent upon particle sizes and particle-to-particle distances. Recent advances in experimental techniques have made it possible to measure the optical response of current-carrying molecular junctions that has laid the groundwork for the development of theoretical formulations, which simultaneously describe both the transport and optical properties of molecular devices. A good test of the parallelizability and portability of the parallelization scheme and a new cluster is to compare data with that obtained on a professionally managed supercomputer facility.
