Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Ryotaro Sano, Mamoru Matsuo, , , | Summary: Recent experiments have shown an indication of a hydrodynamic magnon behavior in ultrapure ferromagnetic insulators; however, its direct observation is still lacking. Here, we derive a set of coupled hydrodynamic equations and study the thermal and spin conductivities for […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Zhaoguang Yi, Zhou Chen, Yunjie Yang, , | Summary: Deep learning has been widely employed to solve the Electrical Impedance Tomography (EIT) image reconstruction problem. Most existing physical model-based and learning-based approaches focus on 2D EIT image reconstruction. However, when they are directly extended to the 3D […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Miguel García-Bravo, Toni Ikonen, Zheng Zhu, , | Summary: In complete metric measure spaces equipped with a doubling measure and supporting a weak Poincar’e inequality, we investigate when a given Banach-valued Sobolev function defined on a subset satisfying a measure-density condition is the restriction of a Banach-valued […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Jong Yeon Lee, Wenjie Ji, Zhen Bi, Matthew P. A. Fisher, | Summary: Measurements allow efficient preparation of interesting quantum many-body states exhibiting long-range, topological, or fractonic orders. Here, we prove that the so-called conformal quantum critical points (CQCP) can be obtained by performing general […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Jong Yeon Lee, Wenjie Ji, Zhen Bi, Matthew P. A. Fisher, | Summary: Measurements allow efficient preparation of interesting quantum many-body states with long-range entanglement, conditioned on additional transformations based on measurement outcomes. Here, we demonstrate that the so-called conformal quantum critical points (CQCP) can […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takumi Funato, Ai Yamakage, Mamoru Matsuo, , | Summary: We theoretically study the generation of spin current due to a surface acoustic wave (SAW) in a superconductor. We model an s-wave superconductor as the mean-field Hamiltonian and calculate spin current generated via spin-vorticity coupling based on kinetic […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Xiaohang Tang, Yi Zhou, Danushka Bollegala, , | Summary: Dynamic contextualised word embeddings represent the temporal semantic variations of words. We propose a method for learning dynamic contextualised word embeddings by time-adapting a pretrained Masked Language Model (MLM) using time-sensitive templates. Given two snapshots $C_1$ and $C_2$ […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Chun-Han Yao, Jimei Yang, Duygu Ceylan, Yi Zhou, Yang Zhou | Summary: Estimating 3D human pose and shape from 2D images is a crucial yet challenging task. While prior methods with model-based representations can perform reasonably well on whole-body images, they often fail when parts of the […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Yunpeng Zhang, Wenzhao Zheng, Zheng Zhu, Guan Huang, Jie Zhou | Summary: 3D object detection with surrounding cameras has been a promising direction for autonomous driving. In this paper, we present SimMOD, a Simple baseline for Multi-camera Object Detection, to solve the problem. To incorporate multi-view information […]
