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 […]
