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 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.

Check out our group's contributions at the APS March meeting. We had a series of interesting seminars covering DCMP, DMP, DQI, and DAMO.

Exciting news as Xueji Wang, Ph.D. student in our group, has been selected as a Defense Advanced Research Projects Agency (DARPA) Riser for 2022. Mr. Wang will participate in the DARPA’s Forward conference series that provides networking opportunities to discover and engage new talents.

Check out our recent work with Nitrogen-vacancy centers which has been published in Optics Letters. We use photonic spin density to induce an effective static magnetic field for NV centers at room temperature. To know more about the paper, click here.

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...

We are delighted to share our recent work on "First-principles study of large gyrotropy in MnBi for infrared thermal photonics", published in Physical Review B. It talks about how nonreciprocal gyrotropic materials have attracted significant interest recently in material physics, nanophotonics, and...
