Kavli Affiliate: Huajia Wang | Summary:Turning on the $TbarT$-deformation in a two-dimensional CFT provides a unique window to study explicitly how non-local features arise in the UV as a result of the deformation. A sharp signature is the dynamical emergence of an effective length-scale $propto sqrtμ$ that separates the local and non-local regimes of the […]
Kavli Affiliate: Xinan Zhou | First 5 Authors: Qi Chen, Qi Chen, , , | Summary: We study the large AdS radius limit of correlation functions in holographic defect CFTs. For two-point functions of operators inserted away from the defect, we derive a position space formula relating a certain scaling limit of the correlators to […]
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 | Summary:We theoretically study spin and valley transport in a transition-metal dichalcogenide(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 band. This process generates a pure valley current which, as […]
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 […]
