NHSE-Driven Coalescence of Topological Defect States in Non-Hermitian Systems
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
In this work, we describe a novel localization phenomena, the so-called topological defect accumulation, occurring in a non-Hermitian chain with an arbitrary number of defect sites…
Topological Zero Modes in Non-Hermitian Topolectrical Systems: Size and Impedance Control
S M Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
We investigate the size-dependent behavior of topological zero modes (TZMs) in finite non-Hermitian Su-Schrieffer-Heeger (SSH) chains implemented on a topolectrical circuit platfor…
Reconfigurable Defect States in Non-Hermitian Topolectrical Chains with Gain and Loss
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md Saddam Hossain Razo +1
We investigate the interplay between the non-Hermitian skin effect (NHSE), parity-time (PT) symmetry, and topological defect states in a finite non-Hermitian Su-Schrieffer-Heeger (…
Exceptional Points and Braiding Topology in Non-Hermitian Systems with long-range coupling
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
We present a study of complex energy braiding in a 1D non-Hermitian system with th order long range asymmetrical coupling. Our work highlights the emergence of novel topological…
Saturation Dynamics in Non-Hermitian Topological Sensing Systems
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
A class of non-Hermitian topological sensors (NTOSs) was recently proposed in which the NTOS comprises a non-Hermitian Su-Schrieffer-Heeger chain with a measurant-dependent couplin…
