Congratulations to Fanglin Bao for his new paper in Optics Letters which talks about - Imaging point sources with low angular separation near or below the Rayleigh criterion are important in astronomy, e.g., in the search for habitable exoplanets near stars. However, the measurement time required to...

Over the past three decades, graphene has become the prototypical platform for discovering topological phases of matter. Both the Chern C ε Z and quantum spin Hall ν ε Z 2 insulators were first predicted in graphene, which led to a veritable explosion of research in topological materials. We...

Classical structured light with controlled polarization and orbital angular momentum (OAM) of electromagnetic waves has varied applications in optical trapping, bio-sensing, optical communications, and quantum simulations. However, quantum noise and photon statistics of three-dimensional photonic...

Congratulations to Fanglin Bao for his contributed talk on “Quantum acceleration in adaptive modal imaging of N stars” which was sessioned for a virtual presentation at the 2021 #OSA Frontiers in Optics + Laser Science Conference.

Congratulations to Ashwin Boddeti on his selection as a finalist for the Emil Wolf Outstanding Student Paper Competition at FIO2021 for the paper titled: Giant Long-Range Dipole-Dipole Interactions in a Plasmonic Lattice in the FiO 3 Quantum Electronics category. The paper talks about the...

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.

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...

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 .
