Revisiting the Affleck-Dine mechanism for primordial black hole formation

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Kai Murai, , | Summary: We study a primordial black hole (PBH) formation scenario based on the Affleck-Dine (AD) mechanism and investigate two PBH mass regions: $M sim 30 M_odot$ motivated by the LIGO-Virgo observations of the binary black hole mergers and $M […]

CHARLES: Channel-Quality-Adaptive Over-the-Air Federated Learning over Wireless Networks

Kavli Affiliate: Jia Liu | First 5 Authors: Jiayu Mao, Haibo Yang, Peiwen Qiu, Jia Liu, Aylin Yener | Summary: Over-the-air federated learning (OTA-FL) has emerged as an efficient mechanism that exploits the superposition property of the wireless medium and performs model aggregation for federated learning in the air. OTA-FL is naturally sensitive to wireless […]

Resolving information loss paradox with Euclidean path integral

Kavli Affiliate: Misao Sasaki | First 5 Authors: Pisin Chen, Misao Sasaki, Dong-han Yeom, Junggi Yoon, | Summary: The information loss paradox remains unresolved ever since Hawking’s seminal discovery of black hole evaporation. In this essay, we revisit the entanglement entropy via Euclidean path integral (EPI) and allow for the branching of semi-classical histories during […]

Linear Sigma Dark Matter

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Dan Kondo, Robert McGehee, Tom Melia, Hitoshi Murayama, | Summary: We present a model of self-interacting dark matter based on QCD-like theories and inspired by the proximity of $a_0(980pm 20)$ to the $Kbar{K}(990)$ threshold. Dark matter is comprised of dark pions which self-scatter via the $sigma$ resonance […]

Non-Universal Stellar Initial Mass Functions: Large Uncertainties in Star Formation Rates at $zapprox 2-4$ and Other Astrophysical Probes

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Joshua J. Ziegler, Thomas D. P. Edwards, Anna M. Suliga, Irene Tamborra, Shunsaku Horiuchi | Summary: We explore the assumption, widely used in many astrophysical calculations, that the stellar initial mass function (IMF) is universal across all galaxies. By considering both a canonical Salpeter-like IMF and a […]

Over-the-Air Federated Learning with Joint Adaptive Computation and Power Control

Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Peiwen Qiu, Jia Liu, Aylin Yener, | Summary: This paper considers over-the-air federated learning (OTA-FL). OTA-FL exploits the superposition property of the wireless medium, and performs model aggregation over the air for free. Thus, it can greatly reduce the communication cost incurred in communicating model […]

New constraint on the tensor-to-scalar ratio from the $Planck$ and BICEP/Keck Array data using the profile likelihood

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Paolo Campeti, Eiichiro Komatsu, , , | Summary: We derive a new upper bound on the tensor-to-scalar ratio parameter $r$ using the frequentist profile likelihood method. We vary all the relevant cosmological parameters of the $Lambda$CDM model, as well as the nuisance parameters. Unlike the Bayesian analysis […]
