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...

Dr. Sathwik Bharadwaj spoke about the concept of photonic frequency (ω) - momentum (q) dispersion that has been extensively studied in artificial dielectric structures such as photonic crystals and metamaterials. However, the ω-q dispersion of electrodynamic excitations hosted in natural materials...

We will host a pico-seminar series with world-leading experts on the topic. While we are biased towards theorists, we will certainly have many experimental speakers as well. How does light interact with matter? The problem has attracted interest over a long time but only now do we have the...

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...

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...

Dr. Zubin Jacob Presented "Heat-Assisted Detection and Ranging (HADAR)" in the ORC Seminar Series 2023. He spoke 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...

This article proposes circular hidden quantum Markov models (c-HQMMs), which can be applied for modeling temporal data. We show that c-HQMMs are equivalent to a tensor network (more precisely, circular local purified state) model. This equivalence enables us to provide an efficient learning model...

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...

To become more pervasive in daily life, quantum technology needs to better detect single particles of light, called photons, carrying quantum information. The problem is that each photon is a very weak signal, making it difficult for measurement devices to efficiently detect them. Purdue University engineers have proposed a new quantum resource that could help design the next generation of single-photon detectors.

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...
