Characterization of a TES-based Anti-Coincidence Detector for Future Large Field-of-View X-ray Calorimetry Missions

Posted by dbos Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Samuel V. Hull, Joseph S. Adams, Simon R. Bandler, Matthew Cherry, James A. Chervenak | Summary: Microcalorimeter instruments aboard future X-ray observatories will require an anti-coincidence (anti-co) detector to veto charged particle events and reduce the non-X-ray background. We have developed a large-format, TES-based prototype anti-coincidence detector […]

NVR: Vector Runahead on NPUs for Sparse Memory Access

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Hui Wang, Zhengpeng Zhao, Jing Wang, Yushu Du, Yuan Cheng | Summary: Deep Neural Networks are increasingly leveraging sparsity to reduce the scaling up of model parameter size. However, reducing wall-clock time through sparsity and pruning remains challenging due to irregular memory access patterns, leading to frequent […]

Unveiling the Interfacial Reconstruction Mechanism Enabling Stable Growth of the Delafossite PdCoO2 on Al2O3 and LaAlO3

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Anna Scheid, Tobias Heil, Y. Eren Suyolcu, Qi song, Niklas Enderlein | Summary: Delafossites, comprised of noble metal (A+) and strongly correlated sublayers (BO2-), form natural superlattices with highly anisotropic properties. These properties hold significant promise for various applications, but their exploitation hinges on the successful […]

Bright hybrid excitons in molecularly tunable bilayer crystals

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tomojit Chowdhury, Aurélie Champagne, Patrick Knüppel, Zehra Naqvi, Ariana Ray | Summary: Bilayer crystals, built by stacking crystalline monolayers, generate interlayer potentials that govern excitonic phenomena but are constrained by fixed covalent lattices and orientations. Replacing one layer with an atomically thin molecular crystal overcomes this […]
