Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Xin Hu, Xin Hu, , , | Summary: We theoretically study spin and valley transport in a TMDC/ferromagnet heterostructure under a perpendicular magnetic field. We find that microwave-driven spin pumping induces a valley-selective spin excitation, a direct consequence of the valley-asymmetric Landau levels in the TMDC conduction […]

Kavli Affiliate: Gang Su | First 5 Authors: Wei Wang, Wei Wang, , , | Summary: We investigate the impact of magnetic flux and the odd-even parity of lattice points $N$ on electron transport in an annular Kitaev chain, with an explanation provided from the energy band perspective. Three transport mechanisms including direct transmission (DT), […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Yimin Hao, Yimin Hao, , , | Summary: The submodular knapsack problem (SKP), which seeks to maximize a submodular set function by selecting a subset of elements within a given budget, is an important discrete optimization problem. The majority of existing approaches to solving the SKP are […]

Kavli Affiliate: Gang Su | First 5 Authors: He-Lin Li, He-Lin Li, , , | Summary: The nonlinear Hall effect (NLHE) can induce optical anisotropy by modifying a material’s dielectric tensor, presenting opportunities for novel characterization and device applications. While the magneto-optical Kerr effect (MOKE) probes the linear Hall effect (LHE) in magnetic materials, an […]

Kavli Affiliate: Bo Gu | First 5 Authors: Songhan Zhao, Songhan Zhao, , , | Summary: In this paper, we consider a semantic-aware reconfigurable intelligent surface (RIS)-assisted wireless network, where multiple semantic users (SUs) simultaneously transmit semantic information to an access point (AP) by using the non-orthogonal multiple access (NOMA) method. The SUs can reshape […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Jiyao Zhang, Jiyao Zhang, , , | Summary: Modern large language models (LLMs) show promising progress in formalizing informal mathematics into machine-verifiable theorems. However, these methods still face bottlenecks due to the limited quantity and quality of multilingual parallel corpora. In this paper, we propose a novel […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Chengan He, Chengan He, , , | Summary: We introduce Digital Salon, a comprehensive hair authoring system that supports real-time 3D hair generation, simulation, and rendering. Unlike existing methods that focus on isolated parts of 3D hair modeling and involve a heavy computation process or network training, […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Pekka Koskela, Pekka Koskela, , , | Summary: We study the relationship between Sobolev extension domains and homogeneous Sobolev extension domains. Precisely, for a certain range of exponents $p$ and $q$, we construct a $(W^1, p, W^1, q)$-extension domain which is not an $(L^1, p, L^1, q)$-extension […]

Kavli Affiliate: Gang Su | First 5 Authors: Shuo Qi, Shuo Qi, , , | Summary: Multipartite entanglement offers a powerful framework for understanding the complex collective phenomena in quantum many-body systems that are often beyond the description of conventional bipartite entanglement measures. Here, we propose a class of multipartite entanglement measures that incorporate the […]

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Xin Theng Lee, Xin Theng Lee, , , | Summary: Altermagnets and compensated ferrimagnets have attracted considerable attention as key building blocks in spintronics devices, owing to their dual advantages of ferromagnets and antiferromagnets. In particular, compensated ferrimagnets exhibit isotropic spin splitting in their electronic and magnon […]
