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…
Strain-Modulated Graphene Heterostructure as a Valleytronic Current Switch
Maverick Chauwin, Zhuo Bin Siu, Mansoor Bin Abdul Jalil
Strain engineering is a promising approach for suppressing the OFF-state conductance in graphene-based devices that arises from Klein tunnelling. In this work, we derive a comprehe…
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…
Zitterbewegung-mediated RKKY coupling in topological insulator thin films
Cong Son Ho, Zhuo Bin Siu, Seng Ghee Tan +1
The dynamics of itinerant electrons in topological insulator (TI) thin films is investigated using a multi-band decomposition approach. We show that the electron trajectory in the…
