Filtering in CMB data analysis with application to ACT DR4 and Planck observations

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Challinor | Summary:Motivated by observed discrepancies between the Atacama Cosmology Telescope Data Release 4 (ACT DR4) and Planck 2018 cosmic microwave background (CMB) anisotropy power spectra, particularly in the cross-correlation of temperature and E-mode polarization, we investigate challenges that may be encountered in the comparison of satellite and ground-based CMB data. In […]

Distinct amplitude mode dynamics upon resonant and off-resonant excitation across the charge density wave energy gap in LaTe3 investigated by time- and angle-resolved photoemission spectroscopy

Posted by klaurent Caltech

Kavli Affiliate: Linda Ye| Summary:Non-equilibrium states generated by ultrafast laser pulses are characterized by specific phenomena that are not accessible in static measurements. Previous time- and angle-resolved photoemission spectroscopy (TARPES) studies on rare-earth tritelluride materials have revealed the laser-driven melting of the charge density wave order as well as its collective amplitude mode excitation. Variation […]

Near-Infrared noise in intense electron bunches

Posted by klaurent Tokyo

Kavli Affiliate: Young-kee Kim | Summary:This article investigates electron bunch density fluctuations in the 1 – 10 $μm$ wavelength range, focusing on their impact on coherent electron cooling (CEC) in hadron storage rings. In this study, we thoroughly compare the shot-noise model with experimental observations of optical transition radiation (OTR) generated by a relativistic electron […]

Algorithmic Strategies for Sustainable Reuse of Neural Network Accelerators with Permanent Faults

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Youssef A. Ait Alama, Sampada Sakpal, Ke Wang, Razvan Bunescu, Avinash Karanth | Summary: Hardware failures are a growing challenge for machine learning accelerators, many of which are based on systolic arrays. When a permanent hardware failure occurs in a systolic array, existing solutions include localizing and […]

Optomechanical vector sensing of new forces at 6 micron separation

Posted by klaurent Stanford

Kavli Affiliate: Giorgio Gratta | Summary:The search for new gravity-like interactions at the sub-millimeter scale is a compelling area of research, with important implications for the understanding of classical gravity and its connections with quantum physics. We report improved constraints on Yukawa-type interactions in the $10,mathrmμm$ regime using optically levitated dielectric microspheres as test masses. […]

Baryogenesis from Primordial CP Violation
