Kavli Affiliate: Stephanie Wehner | First 5 Authors: Guus Avis, Robert Knegjens, Anders S. Sørensen, Stephanie Wehner, | Summary: Restrictions imposed by existing infrastructure can make it hard to ensure an even spacing between the nodes of future fiber-based quantum networks. We here investigate the negative effects of asymmetric node placement by considering separately the […]

Kavli Affiliate: Anthony Challinor | First 5 Authors: Nicholas Choustikov, Zvonimir Vlah, Anthony Challinor, , | Summary: Perturbation theory is a powerful tool for studying large-scale structure formation in the universe and calculating observables such as the power spectrum or bispectrum. However, beyond linear order, typically this is done by assuming a simplification in the […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Yan-Qi Wang, Michał Papaj, Joel E. Moore, , | Summary: Gapless helical edge modes are a hallmark of the quantum spin Hall effect. Protected by time-reversal symmetry, each edge contributes a quantized zero-temperature conductance quantum $G_0 equiv e^2/h$. However, the experimentally observed conductance in WTe$_2$ decreases […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Yongli Zhu, Xiang Zhang, Renchang Dai | Summary: This paper proposes an electronic circuit simulator-based method to accelerate the power system transient simulation, where the modeling of a generic HVDC (High Voltage Direct Current) system is focused. The electronic circuit simulation equations and the backward differentiation formula […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ruoqi Wang, Zhuoyang Chen, Qiong Luo, Feng Wang, | Summary: In radio astronomy, signals from radio telescopes are transformed into images of observed celestial objects, or sources. However, these images, called dirty images, contain real sources as well as artifacts due to signal sparsity and other factors. […]

Stehouwer, Alberto Tosato, Davide Degli Esposti, Davide Costa, Menno Veldhorst | Summary: We grow strained Ge/SiGe heterostructures by reduced-pressure chemical vapor deposition on 100 mm Ge wafers. The use of Ge wafers as substrates for epitaxy enables high-quality Ge-rich SiGe strain-relaxed buffers with a […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lisa V. Drummond, Alexandra G. Hanselman, Devin R. Becker, Scott A. Hughes, | Summary: The study of spinning bodies moving in curved spacetime has relevance to binary black hole systems with large mass ratios, as well as being of formal interest. At zeroth order in a […]
