Supermassive black hole formation from Affleck-Dine mechanism with suppressed clustering on large scales

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Kai Murai, Shunsuke Neda, | Summary: We study a primordial black hole (PBH) formation model based on the framework of the inhomogeneous Affleck-Dine (AD) mechanism, which can explain the seeds of supermassive black holes (SMBHs). This model, however, predicts strong clustering of SMBHs […]

Cosmological Consequences of Unconstrained Gravity and Electromagnetism

Kavli Affiliate: Tom Melia | First 5 Authors: Loris Del Grosso, David E Kaplan, Tom Melia, Vivian Poulin, Surjeet Rajendran | Summary: Motivated by the quantum description of gauge theories, we study the cosmological effects of relaxing the Hamiltonian and momentum constraints in general relativity and Gauss’ law in electromagnetism. We show that the unconstrained […]

Extracting parity-violating gravitational waves from projected tidal force tensor in three dimensions

Kavli Affiliate: Misao Sasaki | First 5 Authors: Teppei Okumura, Misao Sasaki, , , | Summary: Gravitational waves (GWs) may be produced by various mechanisms in the early universe. In particular, if parity is violated, it may lead to the production of parity-violating GWs. In this paper, we focus on GWs on the scale of […]

Finite-Time Convergence and Sample Complexity of Actor-Critic Multi-Objective Reinforcement Learning

Kavli Affiliate: Jia Liu | First 5 Authors: Tianchen Zhou, FNU Hairi, Haibo Yang, Jia Liu, Tian Tong | Summary: Reinforcement learning with multiple, potentially conflicting objectives is pervasive in real-world applications, while this problem remains theoretically under-explored. This paper tackles the multi-objective reinforcement learning (MORL) problem and introduces an innovative actor-critic algorithm named MOAC […]

Understanding Server-Assisted Federated Learning in the Presence of Incomplete Client Participation

Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Peiwen Qiu, Prashant Khanduri, Minghong Fang, Jia Liu | Summary: Existing works in federated learning (FL) often assume an ideal system with either full client or uniformly distributed client participation. However, in practice, it has been observed that some clients may never participate in FL […]
