Multiple asymmetric couplings induced unconventional corner mode in topolectrical circuits
Multiple asymmetric couplings induced unconventional corner mode in topolectrical circuits
Abstract We investigate the emergence of unconventional corner mode in a two-dimensional (2D) topolectrical circuits induced by asymmetric couplings. The non-Hermitian skin effect of two kinked one-dimensional (1D) lattices with multiple asymmetric couplings are explored. Then we extend to the 2D model, derive conditions for the non-Hermitian hybrid skin effect …
