Free-Electron Quantum Optics (Prof. Ido Kaminer, Technion –­­ Israel Institute of Technology)

Dec 08, 2020 from 04:15 PM to 05:45 PM

Zoom video conference

Ido KaminerResearch of cavity quantum electrodynamics (CQED) has enabled new capabilities in quantum optics, quantum computation, and various quantum technologies. So far, all the work in this field has included light interacting with bound-electron systems such as atoms, quantum dots, and quantum circuits. In contrast, free-electron systems enable fundamentally different physical phenomena, as their energy distribution is continuous and not discrete, and allow for tunable transitions and selection rules.

We have developed a platform for studying free-electron CQED at the nanoscale and demonstrated it by observing coherent electron interaction with a photonic cavity for the first time. Our platform includes femtosecond lasers in an ultrafast transmission electron microscope, which created what is, in many respects, the most powerful nearfield optical microscope in the world today. We resolve photonic bandstructures as a function of energy, momentum, and polarization, simultaneously with capturing the spatial distribution of the photonic modes at deep-subwavelength resolution.

These capabilities open new paths toward using free electrons as carriers of quantum information. As examples, we show how to create free-electron qubits and implement quantum gates with femtosecond lasers. We further show how to measure quantum decoherence in space and time using the free-electron quantum interactions. Such interactions also enable new avenues for tunable X-ray sources, as we demonstrate with theory and experiments.

Electromagnetics for Next-Generation Body Area Sensing (Asimina Kiourti, Ohio State University)

Dec 10, 2020 from 04:00 PM to 06:00 PM

Online Meeting

Asimina Kiourti

Rapid advances in bio-electromagnetics and materials are opening new and unexplored opportunities in body area sensing. This talk will discuss next-generation wearables and implants that break the state-of the-art boundaries in terms of seamlessness, capabilities, and performance. Focus will be on research efforts carried out in our group towards: a) functionalized garments that monitor body motion in real-world settings, b) wearable antennas for into-body radiation with unprecedented bandwidth and efficiency, c) portable sensors for capturing the naturally emanated magnetic fields by the human body as a predictor of abnormalities, and d) wireless and batteryless implants for deep-brain sensing. Enabling technologies will also be discussed, with a special focus on embroidered e-textiles. Flexibility and mechanical/thermal robustness associated with such conductive surfaces makes them highly attractive for numerous applications besides garments (e.g., efficient antenna folding and packaging; reconfigurable antenna surfaces; conformal airborne antennas). Our ultimate vision entails unobtrusive wearables and implants employed “in-the-wild” for applications as diverse as healthcare, sports, defense, space, emergency, consumer electronics, and beyond.

How Should We Think About Plasma-Catalysis? Insights from Experiments and Simulations (Prof. Dr. David Go, University of Notre Dame, USA)

Dec 15, 2020 from 04:15 AM to 05:40 PM

Zoom video conference

David GoPlasma-catalysis is an emerging field of plasma science and engineering where non-equilibrium plasmas are coupled with catalytic materials to more effectively drive chemical reactions. The field holds significant promise, with the potential to overcome existing challenges for many industrially-relevant processes, such as the reforming of natural gas or the synthesis of ammonia. However, plasma-catalysis systems are extremely complex, consisting of a wide variety of chemical and physical processes that can both synergistically work together and function in opposition to each other. While plasma chemistry and catalysis are both well studied fields in their own right, when they are coupled, the question arises: How should we think about these systems?  That is, should we think about them as catalysis systems that are enhanced by a plasma or a plasma system that is enhanced by a catalyst? Or should we think about them in a completely different way?  

At the University of Notre Dame, an interdisciplinary team with expertise in plasma science, catalysis, surface science, and atomistic modelling have been trying to answer these questions both at a fundamental level and for what they imply for engineering plasma-catalysis systems. This colloquium talk will present a holistic perspective on our team’s work in this area. I will discuss how our findings have shown how plasma-catalysis diverges from ‘conventional’ thermal catalysis, how plasmas can drive chemical conversion ‘beyond equilibrium’, and the evidence we have that molecular processes – rather than macroscopic effects – help drive these behavior. This talk will set the stage for understanding how to design both catalysts and reactor systems that capitalize on the non-equilibrium conditions in a plasma to enhance chemical conversion.
