Skin-topological effect in two-dimensional nonreciprocal topological superconductor

Autor: Wang, Hong, Lu, Ming, Liu, Jie

We investigate the interplay between non-Hermitian skin effect (NHSE) and topological properties in two-dimensional topological superconductor. Two kinds of non-Hermiticity are considered. The first is the spin-independent non-reciprocal hopping, whi

Best Practices for Distilling Large Language Models into BERT for Web Search Ranking

Autor: Ye, Dezhi, Hu, Junwei, Fan, Jiabin, Tian, Bowen, Liu, Jie, Liang, Haijin, Ma, Jin

Recent studies have highlighted the significant potential of Large Language Models (LLMs) as zero-shot relevance rankers. These methods predominantly utilize prompt learning to assess the relevance between queries and documents by generating a ranked

Quantifying the non-Abelian property of Andreev bound states in inhomogeneous Majorana nanowires

Autor: Zhang, Yu, Wu, Yijia, Liu, Jie, Xie, X. C.

Non-Abelian braiding is a key property of Majorana zero modes (MZMs) that can be utilized for topological quantum computation. However, the presence of trivial Andreev bound states (ABSs) in topological superconductors can hinder the non-Abelian brai
