Quantized Conductance through Surface States in High Quality Three-Dimensional Dirac Semimetal CdAs Nanowire/Nanoribbon p-n Junctions
Sungjin An, Zhuo Bin Siu, Vardan Kaladzhyan +8
We report the observation of quantized conductance in high-mobility three-dimensional Dirac semimetal CdAs nanowire and nanoribbon p-n junctions. By employing suspended dev…
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…
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…
Second-order charge and spin transport in LaO/STO system in the presence of cubic Rashba spin orbit couplings
Zhuo Bin Siu, Anirban Kundu, Mansoor B. A. Jalil
Certain non-centrosymmetric materials with broken time-reversal symmetry may exhibit non-reciprocal transport behavior under an applied electric field in which the charge and spin…
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…
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…
Conductance modulation in Weyl semimetals with tilted energy dispersion without a band gap
Can Yesilyurt, Seng Ghee Tan, Gengchiau Liang +1
We investigate the tunneling conductance of Weyl semimetal with tilted energy dispersion by considering electron transmission through a p-n-p junction with one-dimensional electric…
