Kavli Affiliate: Leon Balents | First 5 Authors: Léo Mangeolle, Lucile Savary, Leon Balents, , | Summary: We systematically derive the quantum kinetic equation in full phase space for any quadratic hamiltonian of bosonic fields, including in the absence of translational invariance. This enables the treatment of boundaries, inhomogeneous systems and states with non-trivial textures, […]
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 […]

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 […]
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 […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Bozhang Dong, Yating Wan, Weng W. Chow, Chen Shang, Artem Prokoshin | Summary: Ultra-low-noise laser sources are crucial for a variety of applications, including microwave synthesizers, optical gyroscopes, and the manipulation of quantum systems. Silicon photonics has emerged as a promising solution for high-coherence applications due […]
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 […]

Kavli Affiliate: Matthew Fisher | First 5 Authors: Vikas Thamizharasan, Difan Liu, Shantanu Agarwal, Matthew Fisher, Michael Gharbi | Summary: We present VecFusion, a new neural architecture that can generate vector fonts with varying topological structures and precise control point positions. Our approach is a cascaded diffusion model which consists of a raster diffusion model […]
