Twisted topology and Bipolar Non-Hermitian Skin Effect induced by long-range asymmetric coupling
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +2
We investigate the twisted topology of the complex eigenspectrum of a one-dimensional non-Hermitian system under the influence of long-range unidirectional coupling. Unlike the com…

Engineering Higher-Order Dirac and Weyl Semimetallic phase in 3D Topolectrical Circuits
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +1
We propose a 3D topolectrical (TE) network that can be tuned to realize various higher-order topological gapless and chiral phases. We first study a higher-order Dirac semimetal ph…
