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 […]
Kavli Affiliate: Austin Joyce | First 5 Authors: James Bonifacio, Kurt Hinterbichler, Austin Joyce, Diederik Roest, | Summary: The special galileon and Dirac-Born-Infeld (DBI) theories are effective field theories of a single scalar field that have many interesting properties in flat space. These theories can be extended to all maximally symmetric spaces, where their algebras […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: We argue that if the Newtonian gravitational field of a body can mediate entanglement with another body, then it should also be possible for the body producing the Newtonian field to entangle directly with on-shell […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Rebecca Diesing, Alexa Bukowski, Noah Friedlander, Alex Miller, Stephan Meyer | Summary: The second generation of the Extreme Universe Space Observatory on a Super Pressure Balloon (EUSO-SPB2) is a balloon instrument for the detection of ultra high energy cosmic rays (UHECRs) with energies above 1 EeV […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Viktoria Kungel, Randy Bachman, Jerod Brewster, Madeline Dawes, Julianna Desiato | Summary: The Extreme Universe Space Observatory – Super Pressure Balloon (EUSO-SPB2) mission will fly two custom telescopes that feature Schmidt optics to measure v{C}erenkov- and fluorescence-emission of extensive air-showers from cosmic rays at the PeV […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Evan McDonough, Meng-Xiang Lin, J. Colin Hill, Wayne Hu, Shengjia Zhou | Summary: We consider the interplay of the Early Dark Energy (EDE) model, the Swampland Distance Conjecture (SDC), and cosmological parameter tensions. EDE is a proposed resolution of the Hubble tension relying upon a near-Planckian scalar […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Rodolfo Capdevilla, David Curtin, Yonatan Kahn, Gordan Krnjaic, | Summary: We comprehensively study all viable new-physics scenarios that resolve the muon $(g-2)_mu$ anomaly with only Standard Model singlet particles coupled to muons. Since such models are only viable in the MeV — TeV mass range and require […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Abigail Lee, , | Summary: We present an absolute calibration of the J-region Asymptotic Giant Branch (JAGB) method using published photometry of resolved stars in 20 nearby galaxies observed with HST using the WFC3-IR camera and the F110W (Broad J-Band) […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Xiaofeng Dong, Nesar Ramachandra, Salman Habib, Katrin Heitmann, Michael Buehlmann | Summary: The potential of deep learning based image-to-image translations has recently drawn a lot of attention; one intriguing possibility is that of generating cosmological predictions with a drastic reduction in computational cost. Such an effort requires […]
Kavli Affiliate: Wayne Hu | First 5 Authors: David Zegeye, Keisuke Inomata, Wayne Hu, , | Summary: Single field inflationary models that seek to greatly enhance small scale power in order to form primordial black holes predict both a squeezed bispectrum that is enhanced by this small scale power and a potentially detectable enhancement of […]
