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 structures such as photonic crystals and metamaterials has led to important advances. This...

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...

Check out our recent News & View article ‘Symmetry breaking in thermal photonics.’ in Light: Science and Applications. Thermal radiation is omnipresent and is engineered for various applications in modern photonics, such as cooling, imaging, and energy harvesting. Symmetries and symmetry breaking...

In our recent work in Optics Express, we discover the quantum analog of the well-known classical maximum power transfer theorem, typically used in classical circuit design. By developing a unified framework, from the Lindblad master equation and describing power delivery in dissipative quantum...

Our work to derive a unified quantum theory of coherent and incoherent energy transfer between two atoms—donor and acceptor—valid in arbitrary Markovian nanophotonic environments is published in Optics Express. By developing an exactly solvable theory for resonance energy transfer from the first...

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...

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...

Quantum causality is an emerging field of study which has the potential to greatly advance our understanding of quantum systems. In this paper, we put forth a theoretical framework for merging quantum information science and causal inference by exploiting entropic principles. For this purpose, we...

Prof Sean Molesky discussed how Lagrange duality heuristics for quadratically constrained quadratic optimization problems (QCQPs) can substantially lessen these knowledge gaps for a variety of common photonic design problems. As showcased by initial applications to topics including radiative...

In this talk, Prof. Ricardo Decca presents our current efforts to perform a measurement of the elusive quantum friction. While there is now a more or less established theoretical picture of the expected friction experienced by a dipole moving in front of a dielectric plate, experimental results are...
