Purdue researchers have made a breakthrough demonstration of controlling energy transfer mediated by vacuum fluctuations. They have proposed and demonstrated a non-reciprocal, diode-like Casimir device. Their results were published in Nature Nanotechnology. A striking prediction of quantum mechanics...

Graphene has been hailed a “wonder material,” given its potential in a growing pool of applications and industries, from quantum computing (also see “Getting edgy with graphene”) to healthcare. But it’s also a bit unassuming. While it’s the thinnest material in the world at just one-atom-thick...

In this talk, the Prof discussed some of the past and ongoing research in the application of machine learning methods to efficiently guide materials design and discovery efforts. The overarching theme is efficient navigation of the vast search space, which is especially critical when brute-force...

Prof Joseph talked about Hyperbolic lattices which are a new form of synthetic quantum matter in which particles effectively hop on a discrete tiling of two-dimensional hyperbolic space, a non-Euclidean space of negative curvature. Hyperbolic tilings were studied by the geometer H.S.M. Coxeter and...

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...

Ashwin Boddeti, a graduate student with Purdue University’s Elmore Family School of Electrical and Computer Engineering, has been awarded the Wolf Outstanding Student Paper Competition by Optica (formerly OSA). Established in 2008 to honor Emil Wolf for his many contributions to science and Optica...

Check out contributions from our group at the CLEO Conference. We had a series of exciting talks given by Xueji Wang, Farid Kalhor, and Ashwin Boddeti.
