Prof Zubin Jacob gave a plenary talk at the physics of quantum electronics conference. He spoke about the recent theory work on Atomistic Maxwell Hamiltonians and the topological optical-N insulator.

Prof. Stephan Haas discussed how the many-body excitation spectrum of topological insulators is affected by the presence of long-range Coulomb interactions. In the one-dimensional Su-Schrieffer-Heeger model and its mirror-symmetric variant, strongly localized plasmonic excitations are observed which...

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 article from Phys.org, discussing our recent work on "Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces" has been published in Science Advances (2023). Spinning thermal radiation is a unique phenomenon observed in condensed astronomical objects...

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...

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...

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...
