Distinct Optical Excitation Mechanisms of a Coherent Magnon in a van der Waals Antiferromagnet

Kavli Affiliate: Leon Balents | First 5 Authors: Clifford J. Allington, Carina A. Belvin, Urban F. P. Seifert, Mengxing Ye, Tommy Tai | Summary: The control of antiferromagnets with ultrashort optical pulses has emerged as a prominent field of research. Tailored laser excitation can launch coherent spin waves at terahertz frequencies, yet a comprehensive description […]

Morphology and Mach Number Dependence of Subsonic Bondi-Hoyle Accretion

Kavli Affiliate: Lars Bildsten | First 5 Authors: Logan J. Prust, Hila Glanz, Lars Bildsten, Hagai B. Perets, Friedrich K. Roepke | Summary: We carry out three-dimensional computations of the accretion rate onto an object (of size $R_{rm sink}$ and mass $m$) as it moves through a uniform medium at a subsonic speed $v_{infty}$. The […]

Learning Continuous 3D Words for Text-to-Image Generation

Kavli Affiliate: Matthew Fisher | First 5 Authors: Ta-Ying Cheng, Matheus Gadelha, Thibault Groueix, Matthew Fisher, Radomir Mech | Summary: Current controls over diffusion models (e.g., through text or ControlNet) for image generation fall short in recognizing abstract, continuous attributes like illumination direction or non-rigid shape change. In this paper, we present an approach for […]

Learning Subject-Aware Cropping by Outpainting Professional Photos

Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Lu Yuan, Michaël Gharbi, Matthew Fisher, Kayvon Fatahalian | Summary: How to frame (or crop) a photo often depends on the image subject and its context; e.g., a human portrait. Recent works have defined the subject-aware image cropping task as a nuanced and practical version […]

Secret extraction attacks against obfuscated IQP circuits

Kavli Affiliate: David Gross | First 5 Authors: David Gross, Dominik Hangleiter, , , | Summary: Quantum computing devices can now perform sampling tasks which, according to complexity-theoretic and numerical evidence, are beyond the reach of classical computers. This raises the question of how one can efficiently verify that a quantum computer operating in this […]
