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...

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.
