BAM: A Balanced Attention Mechanism for Single Image Super Resolution

1 code implementation • 15 Apr 2021 • Fanyi Wang, Haotian Hu, Cheng Shen

The results demonstrate that BAM can efficiently improve the networks performance, and for those originally with attention mechanism, the substitution with BAM further reduces the amount of parameters and increases the inference speed.

Emergence of Chern insulating states in non-Magic angle twisted bilayer graphene

no code implementations • 8 Oct 2020 • Cheng Shen, Jianghua Ying, Le Liu, Jianpeng Liu, Na Li, Shuopei Wang, Jian Tang, Yanchong Zhao, Yanbang Chu, Kenji Watanabe, Takashi Taniguchi, Rong Yang, Dongxia Shi, Fanming Qu, Li Lu, Wei Yang, Guangyu Zhang

For {\theta}=1. 25{\deg}, we observe an emergence of topological insulating states at hole side with a sequence of Chern number |C|=4-|v|, where v is the number of electrons (holes) in moir\'e unite cell.
