Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Hirosi Ooguri, Tadashi Takayanagi, , , | Summary: McNamara and Vafa conjectured that any pair of consistent quantum gravity theories can be connected by a domain wall. We test the conjecture in the context of the AdS/CFT correspondence. There are topological constraints on existence of an interface […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Clarke J. Esmerian, Andrey V. Kravtsov, Zachary Hafen, Claude-Andre Faucher-Giguere, Eliot Quataert | Summary: We examine the thermodynamic state and cooling of the low-$z$ Circum-Galactic Medium (CGM) in five FIRE-2 galaxy formation simulations of Milky Way-mass galaxies. We find that the CGM in these simulations is […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Peter Plavchan, Gautam Vasisht, Chas Beichman, Heather Cegla, Xavier Dumusque | Summary: EarthFinder is a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on a dramatic shift in our understanding of how […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Gang Xu, Fei Gao, He Liu, Rong-Long Ma | Summary: Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in germanium (Ge) intriguing candidates for spin qubits with […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael K. Florian, Jane R. Rigby, Ayan Acharyya, Keren Sharon, Michael D. Gladders | Summary: For studies of galaxy formation and evolution, one of the major benefits of the James Webb Space Telescope is that space-based IFUs like those on its NIRSpec and MIRI instruments will […]
Kavli Affiliate: David Spergel | First 5 Authors: Miles Cranmer, Alvaro Sanchez-Gonzalez, Peter Battaglia, Rui Xu, Kyle Cranmer | Summary: We develop a general approach to distill symbolic representations of a learned deep model by introducing strong inductive biases. We focus on Graph Neural Networks (GNNs). The technique works as follows: we first encourage sparse […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Sauro Succi, Elad Stolovicki, David A. Weitz | Summary: Three-dimensional, time-dependent direct simulations of step emulsification micro-devices highlight two essential mechanisms for droplet formation: first, the onset of an adverse pressure gradient driving a back-flow of the continuous phase from the external […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Silviu-Marian Udrescu, Andrew Tan, Jiahai Feng, Orisvaldo Neto, Tailin Wu | Summary: We present an improved method for symbolic regression that seeks to fit data to formulas that are Pareto-optimal, in the sense of having the best accuracy for a given complexity. It improves on the previous […]
Kavli Affiliate: Paul L. McEuen | First 5 Authors: Baris Bircan, Marc Z. Miskin, Robert J. Lang, Michael C. Cao, Kyle J. Dorsey | Summary: Origami design principles are scale invariant and enable direct miniaturization of origami structures provided the sheets used for folding have equal thickness to length ratios. Recently, seminal steps have been […]
Kavli Affiliate: Subo Dong | First 5 Authors: T. Jayasinghe, C. S. Kochanek, K. Z. Stanek, B. J. Shappee, T. W. -S. Holoien | Summary: The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline (${sim}4$ yrs) $V-$band light curves for sources brighter than V$lesssim17$ mag across the whole sky. We produced V-band light curves […]
