Kavli Affiliate: Long Zhang | First 5 Authors: Xiao-Dong Lin, Xiao-Dong Lin, , , | Summary: The accurate determination of non-Hermitian (NH) topological invariants plays a central role in the study of NH topological phases. In this work, we propose a general framework for directly measuring NH topological invariants in even-dimensional systems with real line […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Liu Liu, Xiaofeng Wang, Guosheng Zhao, Keyu Li, Wenkang Qin | Summary: Imitation Learning has become a fundamental approach in robotic manipulation. However, collecting large-scale real-world robot demonstrations is prohibitively expensive. Simulators offer a cost-effective alternative, but the sim-to-real gap make it extremely challenging to scale. Therefore, […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Naoki Nishimura, Takumi Funato, Mamoru Matsuo, Takeo Kato, | Summary: We theoretically explore the generation of spin current driven by a temperature gradient in a junction between a chiral insulator and a normal metal. Based on the gyromagnetic effect caused by microscopic rotation due to phonons, we […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: , , , , | Summary: We theoretically explore the generation of spin current driven by a temperature gradient in a junction between a chiral insulator and a normal metal. Based on the gyromagnetic response induced by microscopic acoustic-phonon-mediated lattice rotation, we derive a formula for the […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yiping Liu, Yi Zhou, Zhenxiang Xu, Mingyu Xiao, Jin-Kao Hao | Summary: The Generalized Independent Set (GIS) problem extends the classical maximum independent set problem by incorporating profits for vertices and penalties for edges. This generalized problem has been identified in diverse applications in fields such as […]
Kavli Affiliate: Biao Huang | First 5 Authors: Runze Lin, Junghui Chen, Biao Huang, Lei Xie, Hongye Su | Summary: In the era of Industry 4.0 and smart manufacturing, process systems engineering must adapt to digital transformation. While reinforcement learning offers a model-free approach to process control, its applications are limited by the dependence on […]
Kavli Affiliate: Long Zhang | First 5 Authors: Yu Yao, Junhao Zhang, Pu Miao, Long Zhang, Gaojie Chen | Summary: Unlike the conventional fully-passive and fully-active reconfigurable intelligent surfaces (RISs), a hybrid RIS consisting of active and passive reflection units has recently been concerned, which can exploit their integrated advantages to alleviate the RIS-induced path […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Wensi Sun, Yanshuang Chen, Wencheng Ji, Yi Zhou, Hua Tong | Summary: Hierarchical dynamics in glass-forming systems span multiple timescales, from fast vibrations to slow structural rearrangements, appearing in both supercooled fluids and glassy states. Understanding how these diverse processes interact across timescales remains a central challenge. […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Zirui Li, Siwei Wu, Xingyu Wang, Yi Zhou, Yizhi Li | Summary: The rapid advancement of unsupervised representation learning and large-scale pre-trained vision-language models has significantly improved cross-modal retrieval tasks. However, existing multi-modal information retrieval (MMIR) studies lack a comprehensive exploration of document-level retrieval and suffer from […]
