Topological metasurface: From passive toward active and beyond
Jian Wei You, Zhihao Lan, Qian Ma +5
Metasurfaces are subwavelength structured thin films consisting of arrays of units that allow the controls of polarization, phase and amplitude of light over a subwavelength thickn…
Higher-order topological insulator in a modified Haldane-Hubbard model
Tian-Cheng Yi, Hai-Qing Lin, Rubem Mondaini
We investigate the ground-state phase diagram of a modified spinless Haldane-Hubbard model with broken threefold rotational symmetry, employing exact diagonalization calculations.…
Towards Efficient Visual Simplification of Computational Graphs in Deep Neural Networks
Rusheng Pan, Zhiyong Wang, Yating Wei +6
A computational graph in a deep neural network (DNN) denotes a specific data flow diagram (DFD) composed of many tensors and operators. Existing toolkits for visualizing computatio…
Non-trivial band topology and orbital-selective electronic nematicity in a new titanium-based kagome superconductor
Yong Hu, Congcong Le, Zhen Zhao +11
Electronic nematicity that spontaneously breaks rotational symmetry has been shown as a generic phenomenon in correlated quantum systems including high-temperature superconductors…
RAGO: Recurrent Graph Optimizer For Multiple Rotation Averaging
Heng Li, Zhaopeng Cui, Shuaicheng Liu +1
This paper proposes a deep recurrent Rotation Averaging Graph Optimizer (RAGO) for Multiple Rotation Averaging (MRA). Conventional optimization-based methods usually fail to produc…
Can we constrain galaxy geometry parameters using spatially integrated SED fitting?
Yisheng Qiu, Xi Kang, Yu Luo
Sophisticated spectral energy distribution (SED) models describe dust attenuation and emission using geometry parameters. This treatment is natural since dust effects are driven by…
