Kavli Affiliate: Yi Zhou | First 5 Authors: Kaiwen Huang, Kaiwen Huang, , , | Summary: Semi-supervised medical image segmentation is a crucial technique for alleviating the high cost of data annotation. When labeled data is limited, textual information can provide additional context to enhance visual semantic understanding. However, research exploring the use of textual […]
Kavli Affiliate: Long Zhang | First 5 Authors: Hong-Hao Song, Hong-Hao Song, , , | Summary: The one-dimensional (1D) domain wall of 2D $mathbbZ_2$ topological orders is studied theoretically. The Ising domain wall model is shown to have an emergent SU(2)$_1$ conformal symmetry because of a hidden nonsymmorphic octahedral symmetry. While a weak magnetic field […]
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 […]
