Graduate student Farid Kahlor gave a talk on "Quantum Sensing of Photonic Spin Density Using a Single Spin Qubit" at the 2021 OSA Imaging and Applied Optics Congress. You can read more about it in this Arxiv version of the paper.

Researchers have detected the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize winner Lord Rayleigh in 1885. This phenomenon can find applications in acoustic quantum technologies or in so-called “phononic” components, which are used to control the...

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...

Our recent work on ‘Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces’ has been published in Science Advances . We uncover a new method for generating spinning thermal radiation in a controlled & efficient manner using metasurfaces. Spinning thermal...

In this talk, Dr. Chen-Ting Liao introduced the topology of light – the light carrying orbital angular momentum (OAM). The OAM of light can be static, dynamic, or spatiotemporal. Static OAM of light has been known for three decades and has found numerous applications, from optical trapping, and...

Our recent work on 'Heat-assisted detection and ranging' has been published in Nature . We discuss how Machine perception uses advanced sensors to collect information about the surrounding scene for situational awareness . State-of-the-art machine perception using active sonar, radar and LiDAR to...

Our group members, Shoaib Mahmud and Daien He, have been awarded the Bilsland Dissertation Fellowship by Purdue Graduate School. The fellowship is awarded by departments and colleges to PhD students who will enter their final year of their program in 2024. Recipients are expected to devote full-time...

Congratulations to Dr. Xueji Wang and Ziyi Yang for the feature of their recent paper on thermal imaging among the top downloads in Optica for the month of January. In this paper titled "Spinning metasurface stack for spectro-polarimetric thermal imaging", we introduce an approach for spectro...
