Abstract: Exciton-surface plasmon coupling is at the heart of the most elementary light-matter interactions and is a result of not only an intrinsic property of the emitter but that of emitter-environment interaction. Thus, change of electromagnetic environment, as in case of metallic nanoplasmonic structures and an emitter, significantly modifies the near field light-matter interaction, which leads to energy transfer in the form of exciton between metallic nanostructure and the emitter…

Spin dynamics in the topological elemental gray Tin from first principles perspective

Gray Tin is attracting much more interest as a topological quantum material, which has a precisely controlled composition and can be a material for spintronic devices. However, the spin dynamics in



Plasmonic resonances in self-assembled reduced symmetry gold nanorod structures.

Self-assembled plasmonic Dolmen structures consisting of small gold nanorods with a few nanometer gaps are observed to show coherent effects of super-radiance and characteristics of Fano resonance due to the significantly reduced symmetry of the structure.
