Deep ultra-violet plasmonics

News: March 31, 2022
Our work on probing germanium plasmons through momentum-resolved EELS experiments got published in Optics Express. We reveal the metallic nature of Ge in the DUV regime. This new frontier of DUV plasmonics enables the development of DUV devices based on Ge. Read more about the paper here .

Our paper as Editor's Suggestion in Physical Review Research

News: April 05, 2022
Our latest paper on topological optical N-insulators was chosen as Editor’s suggestion in Physical Review Research. We introduce a new family of topological materials with exotic electromagnetic features with obstructions to molecular polarizabilities. Know about the paper here .

Quantum field theory for spin operator of the photon

News: May 31, 2022
Our latest paper reports on the discovery of the photon spin operator. All particles in nature can be classified as fermions or bosons. The key distinguishing characteristic is their spin, an internal angular momentum. We stumbled on the spin operator of bosonic gauge fields using quantum...
