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 .

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.

Our most recent work on "picophotonics" has been featured in Purdue News which says "Light-matter interaction in materials is central to several photonic devices from lasers to detectors. Over the past decade, nanophotonics, the study of how light flows on the nanometer scale in engineered...

Our work on “picophotonics” has been featured in several leading scientific news outlets including optics.org and phys.org . Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in semiconductors like silicon...

In this talk, Prof. Ashwin Ramasubramaniam spoke about the ways in which the intercalation of layered compounds is a promising route for the scalable synthesis of 2D heterostructures with novel emergent optoelectronic properties. It investigates, via first-principles calculations, the intercalation...

Our recent work on 'Limits to Quantum Gate Fidelity from Near-Field Thermal and Vacuum Fluctuations' has been published in Physical Review Applied. We develop a framework to analyze and engineer near-field thermal and vacuum fluctuations in the quantum computing hardware for achieving high-fidelity...

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...
