Protected chaos in a topological lattice
Haydar Sahin, Hakan Akgün, Zhuo Bin Siu +4
The erratic nature of chaotic behavior is thought to erode the stability of periodic behavior, including topological oscillations. However, we discover that in the presence of chao…
Valley Hall Effect and Kink States in Topolectrical Circuits
S M Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +1
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. The TE…
Critical hybridization of skin modes in coupled non-Hermitian chains
S M Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +2
Non-Hermitian topological systems exhibit a plethora of unusual topological phenomena that are absent in the Hermitian systems. One of these key features is the extreme eigenstate…
Unconventional node voltage accumulation in generalized topolectrical circuits with multiple asymmetric couplings
S M Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +2
A non-Hermitian system is characterized by the violation of energy conservation. As a result of unbalanced gain or loss in the forward and backward directions due to non-reciprocal…
Non-Hermitian topological phases and exceptional lines in topolectrical circuits
S M Rafi-Ul-Islam, Zhuo Bin Siu, Mansoor B. A. Jalil
We propose a scheme to realize various non-Hermitian topological phases in a topolectrical (TE) circuit network consisting of resistors, inductors, and capacitors. These phases are…
Transport across a topoelectrical Weyl semimetal heterojunction
S M Rafi-Ul-Islam, Zhuo Bin Siu, Mansoor B. A. Jalil
We propose a general method to realize and calculate the transmission in a Weyl semimetal (WSM) heterostructure by employing a periodic three-dimensional topoelectrical (TE) circui…
