Jehan Shalabi was recently conferred with the prestigious Tau Beta Pi fellowship from nation's second oldest honor's society. The purpose has been to finance, for a select group of members chosen for merit, a year of graduate study at the institutions of their choice. A distinguishing feature of Tau...

Our recent theory work on quantum vacuum radiation has been published in New Journal of Physics. Here, we show that a spinning yttrium iron garnet (YIG) nanosphere near aluminum or YIG slabs generates vacuum radiation with radiation power eight orders of magnitude larger than other metallic or...

We are delighted to share our recent work on "Reducing Effective System Dimensionality with Long-Range Collective Dipole-Dipole Interactions" is published in Physical Review Letters. In this work we demonstrate that a resonant nanophotonic structure modifies the apparent dimensionality in an...

Dr. Zubin Jacob Presents "Heat-Assisted Detection and Ranging (HADAR)" in MRS Boston 2023. He will talk about 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...

We are delighted to share our recent work on “Nonequilibrium Hanbury Brown-Twiss interferometry: Theory and application to binary stars,” published in Physical Review Research. We develop a general formalism of Hanbury Brown and Twiss's experiment for objects at different temperatures. We also apply...

The field of topology or the study of how surfaces behave in different dimensions has profoundly influenced the current understanding of matter. The prime example is the topological insulator, which conducts electricity only on the surface while being completely insulating inside the bulk. Topological insulators behave like a metal, i.e., silver on the surface, but inside, it would behave like glass. These properties are defined using the conductivity or flow of electrons depicting whether there is a highway or a road-block for their motion. One major driver of future applications for topological insulators is in the field of spin-electronic devices since these electrons spin in unison, all aligned with each other while flowing on the surface.

An international research team has used a "thermal metamaterial" to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories.

Congratulations to Yifan and Chinmay on their paper, “Broadband circularly polarized thermal radiation from magnetic Weyl semimetals” being published in Optical Materials Express. The paper demonstrates that a planar slab made of magnetic Weyl semimetal (a class of topological materials) can emit...

Purdue researchers have developed a “topological circulator” that may improve how information is routed and processed on a chip. Graphene has been the focus of intense research in both academic and industrial settings due to its unique electrical conduction properties. As the thinnest material known...

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...
