SOI-Compatible Degenerate Band Edge Photonic Structure: Design Rules and Robustness Analysis
Kessem Zamir Abramovich, Jacob Scheuer
Optical periodic structures exhibiting a degenerate band edge (DBE) are of significant interest for various applications such as switching, sensing, high-power amplification, and l…

On the validity of intermediate tracing in multiple quantum interactions
Reuven Ianconescu, Bin Zhang, Aharon Friedman +2
Interactions between many (initially separate) quantum systems raise the question on how to prepare and how to compute the measurable results of their interaction. When one prepare…

Shape-Dependence of Spontaneous Photon Emission by Quantum Electron Wavepackets and the QED Origin of Bunched Electron Beam Superradiance
Bin Zhang, Reuven Ianconescu, Aharon Friedman +4
It has been shown that the spontaneous emission rate of photons by free electrons, unlike stimulated emission, is independent of the shape or modulation of the quantum electron wav…
