• ### New binary black hole mergers in the LIGO-Virgo O3a data

Author(s): Seth Olsen, Tejaswi Venumadhav, Jonathan Mushkin, Javier Roulet, Barak Zackay, and Matias Zaldarriaga The present paper applies a refined detection pipeline to publicly available LIGO-Virgo data from the first half of the third observing run (O3a) to identify new binary black hole (BBH) mergers. The study adds ten new BBH mergers to existing catalogs and provides further evidence for the significance level of previously identified events...
• ### Improved measurement of neutrino oscillation parameters by the NOvA experiment

Author(s): M. A. Acero et al. (The NOvA Collaboration) Long-baseline neutrino experiments are paving the way for the solution of two outstanding puzzles in neutrino physics—mass ordering and charge-parity violation. [Phys. Rev. D 106, 032004] Published Wed Aug 03, 2022
• ### Phonon-mediated Migdal effect in semiconductor detectors

Author(s): Zheng-Liang Liang, Chongjie Mo, Fawei Zheng, and Ping Zhang This paper presents a novel treatment of the dark matter induced Migdal effect in solids, providing a full theoretical description of it as a phonon mediated process. This allows the authors to make reliable predictions for dark matter masses below 50 MeV, where the previously used approximation of assuming the nuclei to be freely recoiling breaks down. [Phys. Rev. D 106...
• ### Flat space analog for the quantum origin of structure

Author(s): Daniel Green and Yiwen Huang The authors address the question of if the structure of the universe originates from quantum fluctuation, as assumed in inflation, or if classical, thermal fluctuations could lead to the same outcome. They study their previously proposed test (the analytical structure of particular cosmological correlation functions) in flat space where several aspects and details are much better defined. They show that...
• ### Phonon background from gamma rays in sub-GeV dark matter detectors

Author(s): Kim V. Berghaus, Rouven Essig, Yonit Hochberg, Yutaro Shoji, and Mukul Sholapurkar Semiconductor based searches for dark matter are a promising route to look for low-mass (sub-GeV) particles, but they present challenges due to their sensitivity. This article analyzes the background from radiogenic photons, which can leave a phonon signal in the detector. The authors find this is a significant effect, which will require active veto strategies...
• ### Ionization of gravitational atoms

Author(s): Daniel Baumann, Gianfranco Bertone, John Stout, and Giovanni Maria Tomaselli Distinctive features of gravitational-wave signals from black hole mergers could reveal the existence of long-sought ultralight bosons. [Phys. Rev. D 105, 115036] Published Mon Jun 27, 2022
• ### Noninvertible duality defects in $3+1$ dimensions

Author(s): Yichul Choi, Clay Córdova, Po-Shen Hsin, Ho Tat Lam, and Shu-Heng Shao A novel kind of generalized global symmetries is uncovered in a large class of familiar 3+1-dimensional gauge theories, including the free Maxwell theory and Yang-Mills gauge theories. These new symmetries, known as the non-invertible global symmetries, do not have inverses and thus go beyond the traditional paradigm of (anti-)unitary transformations. They are implemented...
