Dr. Robert-Jan Slager covered a selection of our recent work on topological characterizations in a rather colloquial style. In particular, he reviewed how constraints on symmetry eigenvalues can directly be linked to topological invariants, reproducing involved K-theory evaluations from a simple...

Our recent publication on long-range dipole-dipole interactions has featured as an online cover in Nano Letters. The paper shows that unique hybrid plasmonic lattice modes mediate dipole-dipole interactions between two different types of molecules over separation distances of ~800 nm. This is in...

In the given talk, Prof. Naik spoke about quantum materials possessing a complex energy landscape arising from the competition between many microscopic processes. A stimulus such as light can tip the delicate balance between these competing processes resulting in novel optical phenomena...

Excited to announce that our work on “Observation and control of Casimir effects in a sphere-plate sphere system” is published in Nature. Here, we experimentally demonstrate an object under the Casimir force exerted by two other objects simultaneously. Using our unique sphere-plate-sphere Casimir...

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...

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...
