System size dependent topological zero modes in coupled topolectrical chains

SM Rafi-Ul-Islam, ZB Siu, H Sahin, CH Lee, MBA Jalil - Physical Review B, 2022 - APS
In this paper, we demonstrate the emergence and disappearance of topological zero modes
(TZMs) in a coupled topolectrical (TE) circuit lattice. Specifically, we consider non-Hermitian …

Valley Hall effect and kink states in topolectrical circuits

SM Rafi-Ul-Islam, ZB Siu, H Sahin, MBA Jalil - Physical Review Research, 2023 - APS
We investigate the emergence of topological valley Hall and kink states in a two-
dimensional topolectrical (TE) model as a result of broken chiral and reflection symmetries …
