Experimental evidence for orbital magnetic moments generated by moiré-scale current loops in twisted bilayer graphene
Si-Yu Li, Yu Zhang, Ya-Ning Ren +3
A remarkable property of twisted bilayer graphene (TBG) with small twist angle is the presence of a well-defined and conserved low-energy valley degrees of freedom1, which can pote…
Observation of the and search for the in
M. Ablikim, M. N. Achasov, P. Adlarson +473
Using a sample of events collected with the BESIII detector, we perform a study of . The is observed in the invari…
No existence of the geometric potential for a Dirac fermion on two-dimensional curved surfaces of revolution
Z. Q. Yang, X. Y. Zhou, Z. Li +2
For a free particle that non-relativistically moves on a curved surface, there are curvature-induced quantum potentials that significantly influence the surface quantum states, but…
Three-dimensional higher-order topological acoustic system with multidimensional topological states
Baizhan Xia, Shengjie Zheng, Liang Tong +3
Topologically protected gapless edge/surface states are phases of quantum matter which behave as massless Dirac fermions, immunizing against disorders and continuous perturbations.…
One-Stage Inpainting with Bilateral Attention and Pyramid Filling Block
Hongyu Liu, Bin Jiang, Wei Huang +1
Recent deep learning based image inpainting methods which utilize contextual information and two-stage architecture have exhibited remarkable performance. However, the two-stage ar…
Frequency tunable topological edge states of two-dimensional honeycomb lattice photonic crystals
Yuchen Peng, Bei Yan, Jianlan Xie +5
In this paper, the photonic quantum spin Hall effect (PQSHE) is realized in dielectric two-dimensional (2D) honeycomb lattice photonic crystal (PC) by stretching and shrinking the…
