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...

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...

Published in PR Applied, our recent work develops the theoretical and computational framework to analyze the spin angular momentum of thermal radiation from bodies with nonuniform temperature profiles. By considering a sample problem of a long silica wire held under a temperature gradient within its...

Our work on “picophotonics” has been featured in several leading scientific news outlets including optics.org and phys.org. Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in semiconductors like silicon...

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...
