Supermassive Primordial Black Holes From Inflation

Kavli Affiliate: Gordan Krnjaic, Albert Stebbins | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, Albert Stebbins, | Summary: There is controversy surrounding the origin and evolution of our universe’s largest supermassive black holes (SMBHs). In this study, we consider the possibility that some of these black holes formed from the direct collapse of […]

Reinforcement Learning for Sequential Decoding of Generalized LDPC Codes

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, David G. M. Mitchell, , , | Summary: In this work, we propose reinforcement learning (RL) for sequential decoding of moderate length generalized low-density parity-check (GLDPC) codes. Here, sequential decoding refers to scheduling all the generalized constraint nodes (GCNs) and single parity-check nodes (SPCNs) of […]

Non-Supersymmetric Heterotic Strings on a Circle

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Bernardo Fraiman, Mariana Graña, Héctor Parra De Freitas, Savdeep Sethi, | Summary: Motivated by a recent construction of non-supersymmetric $text{AdS}_3$, we revisit the $O(16)times O(16)$ heterotic string compactified on a torus. The string one-loop potential energy has interesting dependence on the classical moduli; extrema of this potential […]
