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…
Radio-Frequency Detection of Fabry-Pérot Interference and Quantum Capacitance in Long-Channel Three-Dimensional Dirac Semimetal Cd3As2 Nanowires
Sung Jin An, Jisu Kim, Myung-Chul Jung +10
We demonstrate phase-coherent transport in suspended long-channel Cd3As2 nanowire devices using both direct current (DC) transport and radio-frequency (RF) reflectometry measuremen…
NHSE-Driven Coalescence of Topological Defect States in Non-Hermitian Systems
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
In this work, we describe a novel localization phenomena, the so-called topological defect accumulation, occurring in a non-Hermitian chain with an arbitrary number of defect sites…
Reconfigurable Defect States in Non-Hermitian Topolectrical Chains with Gain and Loss
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md Saddam Hossain Razo +1
We investigate the interplay between the non-Hermitian skin effect (NHSE), parity-time (PT) symmetry, and topological defect states in a finite non-Hermitian Su-Schrieffer-Heeger (…
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…
