Isolated nearly flat higher Chern band in monolayer transition metal trihalides

Kavli Affiliate: Jing Wang | First 5 Authors: Kejie Bao, Huan Wang, Yadong Jiang, Haosheng Xu, Jing Wang | Summary: The interplay between non-trivial topology and strong electron interaction can generate a variety of exotic quantum matter. Here we theoretically propose that monolayer transition metal trihalides MoF$_3$ and WI$_3$ have isolated nearly flat band near […]

Enhanced Monochromatic Photon Emission from Millicharged Co-Interacting Dark Matter

Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We study a millicharged co-interacting dark matter scenario, where the primary dark matter constituent is the dark photon $A’$ and the secondary component is the fermion $chi$. In this model, $chi$ interacts with $A’$ via a $U(1)’$ […]

Bayesian Diffusion Models for 3D Shape Reconstruction

Kavli Affiliate: Xiang Zhang | First 5 Authors: Haiyang Xu, Yu Lei, Zeyuan Chen, Xiang Zhang, Yue Zhao | Summary: We present Bayesian Diffusion Models (BDM), a prediction algorithm that performs effective Bayesian inference by tightly coupling the top-down (prior) information with the bottom-up (data-driven) procedure via joint diffusion processes. We show the effectiveness of […]

Investigating model dependencies for obscured Active Galactic Nuclei: a case study of NGC 3982

Kavli Affiliate: Claudio Ricci | First 5 Authors: KristĂ­na Kallová, Peter G. Boorman, Claudio Ricci, , | Summary: X-ray spectroscopy of heavily obscured Active Galactic Nuclei (AGN) offers a unique opportunity to study the circum-nuclear environment of accreting supermassive black holes (SMBHs). However, individual models describing the obscurer have unique parameter spaces that give distinct […]

Non-uniform contextual interactions in the visual cortex place fundamental limits on spatial vision

Kavli Affiliate: Anirvan Nandy | Authors: Mitchell P Morton, Sachira Denagamage, Nyomi V Hudson and Anirvan S Nandy | Summary: A prevailing assumption in our understanding of how neurons in the primary visual cortex (V1) integrate contextual information is that such processes are spatially uniform. Conversely, perceptual phenomena such as visual crowding, the impaired ability […]
