Observation of High-Order Quantum Pancharatnam-Berry Phase with Structured Photons
Shuang-Yin Huang, He Jiang, Zhi-Cheng Ren +6
When a quantum system evolves so that it returns to its initial state, it will acquire a geometric phase acting as a memory of the transformation of a physical system, which has be…
Self-Attention Assistant Classification of Non-Hermitian Phases in Two-Dimensional Lattice
Hengxuan Jiang, Xiumei Wang, Xingping Zhou
Classification of the non-Hermitian phases in high-dimensional lattice becomes challenging due to interplay of the band topology and non-Hermiticity. The significant increase in da…
Multiple asymmetric couplings induced unconventional corner mode in topolectrical circuits
Hengxuan Jiang, Xiumei Wang, Jie Chen +1
We investigate the emergence of unconventional corner mode in a two-dimensional topolectrical circuits induced by asymmetric couplings. The non-Hermitian skin effect of two kinked…
Deep learning for the design of non-Hermitian topolectrical circuits
Xi Chen, Jinyang Sun, Xiumei Wang +3
Non-Hermitian topological phases can produce some remarkable properties, compared with their Hermitian counterpart, such as the breakdown of conventional bulk-boundary corresponden…
