RELDEC: Reinforcement Learning-Based Decoding of Moderate Length LDPC Codes

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, Allison Beemer, Joerg Kliewer, , | Summary: In this work we propose RELDEC, a novel approach for sequential decoding of moderate length low-density parity-check (LDPC) codes. The main idea behind RELDEC is that an optimized decoding policy is subsequently obtained via reinforcement learning based on […]

One Small Step for an Inflaton, One Giant Leap for Inflation: a novel non-Gaussian tail and primordial black holes

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yi-Fu Cai, Xiao-Han Ma, Misao Sasaki, Dong-Gang Wang, Zihan Zhou | Summary: We report a novel prediction from single-field inflation that even a tiny step in the inflaton potential can change our perception of primordial non-Gaussianities of the curvature perturbation. Our analysis focuses on the tail of […]

A FAST Survey of HINSA in PGCCs Guided by HC3N

Kavli Affiliate: Ke Wang | First 5 Authors: Xunchuan Liu, Yuefang Wu, Chao Zhang, Ningyu Tang, Tie Liu | Summary: Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we search for HI narrow-line self-absorption (HINSA) features in twelve Planck Galactic cold clumps (PGCCs), one starless core L1521B and four star forming sources. Eight of the […]

On the Detection of QCD Axion Dark Matter by Coherent Scattering

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Hajime Fukuda, Satoshi Shirai, , , | Summary: The QCD axion is a promising candidate of the dark matter. In this paper, we discuss elastic scattering processes between nucleons and the QCD axion dark matter. We point out that the cross section can be enhanced by more […]

TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs

Kavli Affiliate: Avi Shporer | First 5 Authors: Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson, Bryson L. Cale, Dax L. Feliz | Summary: We validate the presence of a two-planet system orbiting the 0.2–1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune (TOI 560 b, […]

A Linear Relation Between the Color Stretch $s_{BV}$ and the Rising Color Slope $s_0^*(B-V)$ of Type Ia Supernovae

Kavli Affiliate: Subo Dong | First 5 Authors: Ping Chen, Subo Dong, Chris Ashall, S. Benetti, D. Bersier | Summary: Using data from the Complete Nearby ($z_{host}<0.02$) sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the $B-V$ color curves of Type Ia supernovae: the "color stretch" $s_{BV}$ […]

Direct visualization of electronic transport in a quantum anomalous Hall insulator

Kavli Affiliate: Katja C. Nowack | First 5 Authors: G. M. Ferguson, Run Xiao, Anthony R. Richardella, David Low, Nitin Samarth | Summary: A quantum anomalous Hall (QAH) insulator is characterized by quantized Hall and vanishing longitudinal resistances at zero magnetic field that are protected against local perturbations and independent of sample details. This insensitivity […]
