Waveguiding in two-dimensional Floquet non-Abelian topological insulators
Yujie Zhou, Changsen Li, Xiumei Wang +1
Topological phases characterized by non-Abelian charges have garnered increasing attention recently. Although Floquet (periodic-driving) higher-order topological phases have been e…

Observation of Klein bottle quadrupole topological insulators in electric circuits
Xizhou Shen, Keyu Pan, Xiumei Wang +1
The Klein bottle Benalcazar-Bernevig-Hughes (BBH) insulator phase plays a pivotal role in understanding higher-order topological phases. The insulator phase is characterized by a u…

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…
