Classifying Topology via Edge-State Pure Thermalization
Fatih Ozaydin, Haydar Sahin, Armando Perez-Leija +4
Repeated-interaction machines distinguish heat-like from work-like resources through the steady states they generate, but whether topology can control this distinction remains unkn…
Topolectrical circuits recent experimental advances and developments
Haydar Sahin, Mansoor B. A. Jalil, Ching Hua Lee
Metamaterials serve as versatile platforms for demonstrating condensed matter physics and non-equilibrium phenomena, with electrical circuits emerging as a particularly compelling…
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…
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…
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…
Impedance responses and size-dependent resonances in topolectrical circuits via the method of images
Haydar Sahin, Zhuo Bin Siu, S. M. Rafi-Ul-Islam +3
Resonances in an electric circuit occur when capacitive and inductive components are present together. Such resonances appear in admittance measurements depending on the circuit's…
System size dependent topological zero modes in coupled topolectrical chains
S M Rafi-Ul-Islam, Zhuo Bin Siu, Haydar Sahin +2
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-Hermit…
Anomalous fractal scaling in two-dimensional electric networks
Xiao Zhang, Boxue Zhang, Haydar Sahin +6
Much of the qualitative nature of physical systems can be predicted from the way it scales with system size. Contrary to the continuum expectation, we observe a profound deviation…
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…
