A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654

Posted by klaurent June 13, 2023MIT

Kavli Affiliate: Christopher Burke | Summary:We report the discovery and Doppler mass measurement of a 7.4-day 2.3-$R_oplus$ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIRES spectrum, the Gaia parallax, and multi-wavelength photometry from the ultraviolet to the mid-infrared, we found that the host star has $T_texteff=4174^+34_-42$ K, $logg=4.62^+0.02_-0.03$, $[textFe/H]=-0.58pm0.18$, […]

Emergent conformal boundaries from finite-entanglement scaling in matrix product states

Posted by dbos June 13, 2023UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Rui-Zhen Huang, Long Zhang, Andreas M. Läuchli, Jutho Haegeman, Frank Verstraete | Summary: The use of finite entanglement scaling with matrix product states (MPS) has become a crucial tool for studying 1+1d critical lattice theories, especially those with emergent conformal symmetry. We argue that finite entanglement introduces […]

Applications of Deep Learning to physics workflows

Posted by klaurent June 13, 2023MIT

Kavli Affiliate: George Ricker | First 5 Authors: Manan Agarwal, Jay Alameda, Jeroen Audenaert, Will Benoit, Damon Beveridge | Summary: Modern large-scale physics experiments create datasets with sizes and streaming rates that can exceed those from industry leaders such as Google Cloud and Netflix. Fully processing these datasets requires both sufficient compute power and efficient […]

Dark Matter Search with a Resonantly-Coupled Hybrid Spin System

Posted by dbos June 13, 2023Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Kai Wei, Zitong Xu, Yuxuan He, Xiaolin Ma, Xing Heng | Summary: Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of dark matter (DM). Traditional axion DM experiments rely on sharp resonance, resulting in extensive scanning time to cover a wide mass […]

Dark matter search with a strongly-coupled hybrid spin system

Posted by klaurent June 13, 2023Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Kai Wei, Zitong Xu, Yuxuan He, Xiaolin Ma, Xing Heng | Summary: Observational evidence suggests the existence of dark matter (DM), which comprises approximately $84.4%$ of matter in the universe. Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of DM. Our experiment […]

Universal Asymptotics for High Energy CFT Data

Posted by klaurent June 13, 2023Tokyo

Kavli Affiliate: Hirosi Ooguri | Summary:Equilibrium finite temperature observables of a CFT can be described by a local effective action for background fields — a "thermal effective action." This effective action determines the asymptotic density of states of a CFT as a detailed function of dimension and spin. We discuss subleading perturbative and nonperturbative corrections […]

Turbulence Supported Massive Star Envelopes

Posted by klaurent June 13, 2023UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: William Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: The outer envelopes of massive ($Mgtrsim10,M_{odot}$) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional models predict density inversions and supersonic motions that […]

Skill Disentanglement for Imitation Learning from Suboptimal Demonstrations

Posted by klaurent June 13, 2023June 26, 2023Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Wenchao Yu, Suhang Wang, Lu Wang, Xiang Zhang | Summary: Imitation learning has achieved great success in many sequential decision-making tasks, in which a neural agent is learned by imitating collected human demonstrations. However, existing algorithms typically require a large number of high-quality demonstrations that […]
