Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Chang-Tse Hsieh, Yu Nakayama, Yuji Tachikawa, , | Summary: We show that there is a fermionic minimal model, i.e. a 1+1d conformal field theory which contains operators of half-integral spins in its spectrum, for each $c=1-6/m(m+1)$, $mge 3$. This generalizes the Majorana fermion for $c=1/2$, $m=3$ and […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: DES Collaboration, Tim Abbott, Michel Aguena, Alex Alarcon, Sahar Allam | Summary: We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear and source photometric redshifts […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi, Dylan Nelson, Anna Pasquali | Summary: We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodynamical simulations IllustrisTNG. In particular, we quantify environmental effects on […]
Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Seng Huat Lee, David Graf, Yanglin Zhu, Hemian Yi, Samuel Ciocys | Summary: The discovery of Weyl semimetals (WSMs) has fueled tremendous interest in condensed matter physics. WSMs require breaking of either inversion symmetry (IS) or time-reversal symmetry (TRS); they can be categorized into type-I and type-II […]
Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Roger D. Blandford, , , | Summary: Biological molecules chose one of two structurally, chiral systems which are related by reflection in a mirror. It is proposed that this choice was made, causally, by magnetically polarized and physically chiral cosmic-rays, which are known to […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Hao Chen, Rupak Mahapatra, Glenn Agnolet, Michael Nippe, Minjie Lu | Summary: The detection of a single quantum of energy with high efficiency and low false positive rate is of considerable scientific interest, from serving as single quantum sensors of optical and infra-red photons to enabling the […]
Kavli Affiliate: Peter Ford | First 5 Authors: Cédric Colas, Tristan Karch, Nicolas Lair, Jean-Michel Dussoux, Clément Moulin-Frier | Summary: Developmental machine learning studies how artificial agents can model the way children learn open-ended repertoires of skills. Such agents need to create and represent goals, select which ones to pursue and learn to achieve them. […]

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Karthikeya S. Parunandi, Aayushman Sharma, Raman Goyal, Suman Chakravorty | Summary: The problem of Reinforcement Learning (RL) in an unknown nonlinear dynamical system is equivalent to the search for an optimal feedback law utilizing the simulations/ rollouts of the dynamical system. Most RL techniques search […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: , , , , | Summary: We present a novel unifying interpretation of excess event rates observed in several dark matter direct-detection experiments that utilize single-electron threshold semiconductor detectors. Despite their different locations, exposures, readout techniques, detector composition, and operating depths, these experiments all observe statistically significant […]
