Kavli Affiliate: Misao Sasaki | First 5 Authors: Jaume Garriga, Jaume Garriga, , , | Summary: Spectator fields which provide additional tensor degrees of freedom, on top of the standard metric tensor perturbations, can produce significant amounts of gravitational waves (GWs). Employing the effective field theory approach for spin-2 fields, we find a universal prediction […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Jiakang Bao, Jiakang Bao, , , | Summary: We derive an exact residue formula for the elliptic genera of 2d $mathcalN=(0,1)$ gauge theories. We find a new residue prescription which recovers the Jeffery-Kirwan residue prescription for $mathcalN=(0,2)$ theories. We apply the formula to the Gukov-Pei-Putrov model and […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Yuji Tachikawa, , , | Summary: We construct a new invariant of two-dimensional $mathcalN=(0,1)$ supersymmetric quantum field theories (SQFTs), under a couple of assumptions on the general properties of such SQFTs motivated by considerations in heterotic string theory. This new invariant is in addition to […]
Kavli Affiliate: Tom Melia | First 5 Authors: Bailey Kohn, Bailey Kohn, , , | Summary: The detection of a single quantum of energy with high efficiency and a low false positive rate is of considerable scientific interest, from serving as single quantum sensors of optical and infra-red photons to enabling the direct detection of […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Yusuke Mikura, Yusuke Mikura, , , | Summary: Gravitational waves (GWs) distort galaxy shapes through the tidal effect, offering a novel avenue to probe the nature of gravity. In this paper, we investigate how extra GW polarizations beyond those predicted by general relativity imprint observable signatures on […]
Kavli Affiliate: John Silverman | First 5 Authors: John Silverman, John Silverman, , , | Summary: The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The James Webb Space Telescope (JWST) has opened such investigations by detecting the […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Drew Jamieson, Drew Jamieson, , , | Summary: We present primordial non-Gaussianity predictions from a new high-precision code for simulating axion-U(1) inflation on a discrete lattice. We measure the primordial scalar curvature power spectrum and bispectrum from our simulations, determining their dependence on both scale and axion-gauge […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Katrin Becker, Katrin Becker, , , | Summary: There exists a rare class of R-symmetry gauged $N=(1,0)$ supergravities in six dimensions with gauge group $Gtimes U(1)_R$, where $G$ is semisimple with rank greater than one, and the number of tensor multiplets $n_T=1$, which are free from all […]
Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Fnu Hairi, , , | Summary: In many multi-objective reinforcement learning (MORL) applications, being able to systematically explore the Pareto-stationary solutions under multiple non-convex reward objectives with theoretical finite-time sample complexity guarantee is an important and yet under-explored problem. This motivates us to take the […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Taisei Terawaki, Taisei Terawaki, , , | Summary: Galaxy-galaxy weak lensing provides a powerful means of measuring the average matter distribution around lens galaxies — i.e., the galaxy bias relation. Properly accounting for the spin-2 nature of weak lensing distortions, we develop a quadratic estimator for measuring […]
