Cobordism Conjecture in AdS

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 […]

Thermal Instability in the CGM of $L_{star}$ Galaxies: Testing “Precipitation” Models with the FIRE Simulations

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 […]

Ultrafast coherent control of a hole spin qubit in a germanium quantum dot

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 […]

Spatial Variation in Strong Line Ratios and Physical Conditions in Two Strongly-Lensed Galaxies at z~1.4

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 […]

Discovering Symbolic Models from Deep Learning with Inductive Biases

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 […]

AI Feynman 2.0: Pareto-optimal symbolic regression exploiting graph modularity

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 […]
