September 29, 2020Sabyasachi's work on topological resonator appeared in PRB editor's suggestion.
May 13, 2020Topological physics has introduced a modern design principle in optics, providing build-in protection to specific types of disorder. This work demonstrates how such principles could be used to create a topological resonator in nanophotonic crystals so as to enable chiral light-matter interaction in the context of cavity quantum electrodynamics.
