Low Energy Spread Attosecond Bunching and Coherent Electron Acceleration in Dielectric Nanostructures

Kavli Affiliate: Robert L. Byer | First 5 Authors: Uwe Niedermayer, Dylan S. Black, Kenneth J. Leedle, Yu Miao, Robert L. Byer | Summary: We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon […]

Dark Energy Survey Year 1 Results: Constraining Baryonic Physics in the Universe

Kavli Affiliate: Aaron Roodman | First 5 Authors: Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum, Gary M. Bernstein, Anqi Chen | Summary: Measurements of large-scale structure are interpreted using theoretical predictions for the matter distribution, including potential impacts of baryonic physics. We constrain the feedback strength of baryons jointly with cosmology using weak lensing and galaxy […]

Nearest Neighbor distributions: new statistical measures for cosmological clustering

Kavli Affiliate: Tom Abel | First 5 Authors: Arka Banerjee, Tom Abel, , , | Summary: The use of summary statistics beyond the two-point correlation function to analyze the non-Gaussian clustering on small scales is an active field of research in cosmology. In this paper, we explore a set of new summary statistics — the […]
