Kavli Affiliate: Matthew Fisher | First 5 Authors: Difan Liu, Sandesh Shetty, Tobias Hinz, Matthew Fisher, Richard Zhang | Summary: We present ASSET, a neural architecture for automatically modifying an input high-resolution image according to a user’s edits on its semantic segmentation map. Our architecture is based on a transformer with a novel attention mechanism. […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Tom Monnier, Matthew Fisher, Alexei A. Efros, Mathieu Aubry, | Summary: Approaches to single-view reconstruction typically rely on viewpoint annotations, silhouettes, the absence of background, multiple views of the same instance, a template shape, or symmetry. We avoid all of these supervisions and hypotheses by leveraging explicitly […]

Kavli Affiliate: Leon Balents | First 5 Authors: Yishuai Xu, Zhuoliang Ni, Yizhou Liu, Brenden R. Ortiz, Stephen D. Wilson | Summary: The kagome lattice provides a fascinating playground to study geometrical frustration, topology and strong correlations. The newly discovered kagome metals AV$_3$Sb$_5$ (A=K, Rb, Cs) exhibit various interesting phenomena including topological band structure and […]

Kavli Affiliate: Leon Balents | First 5 Authors: Zhu-Xi Luo, Urban F. P. Seifert, Leon Balents, , | Summary: When two layers of two-dimensional materials are assembled with a relative twist, moir’e patterns arise, inducing a tremendous wealth of exotic phenomena. In this work, we consider twisting two triangular lattices hosting Dirac quantum spin liquids. […]
Kavli Affiliate: Leon Balents | First 5 Authors: Leon Balents, , , , | Summary: We show that triangle-based antiferromagnets with "anti-chiral" order display a non-trivial dependence of the spin orientation with an in-plane field. The spins evolve from rotating in the opposite sense to the field at very low fields to rotating in the […]
Kavli Affiliate: Leon Balents | First 5 Authors: Léo Mangeolle, Leon Balents, Lucile Savary, , | Summary: We study the intrinsic scattering of phonons by a general quantum degree of freedom, i.e. a fluctuating "field" $Q$, which may have completely general correlations, restricted only by unitarity and translational invariance. From the induced scattering rates, we […]
Kavli Affiliate: Leon Balents | First 5 Authors: Urban F. P. Seifert, Mengxing Ye, Leon Balents, , | Summary: Optical pump-probe experiments carried out in the time domain reveal both the intrinsic low energy dynamics and its connections to higher energy excitations in correlated electron systems. In this work, we propose two microscopic mechanisms for […]
