Floquet engineering of topological phase transitions in quantum spin Hall - system
Kok Wai Lee, Mateo Jalen Andrew Calderon, Xiang-Long Yu +3
Floquet engineering of topological phase transitions driven by a high-frequency time-periodic field is a promising approach to realizing new topological phases of matter distinct f…
Observation of higher-order time-dislocation topological modes
Jia-Hui Zhang, Feng Mei, Yi Li +4
Topological dislocation modes resulting from the interplay between spatial dislocations and momentum-space topology have recently attracted significant interest. Here, we theoretic…
Transverse Cooper-Pair Rectifier
Pei-Hao Fu, Yong Xu, Jun-Feng Liu +2
Non-reciprocal devices are key components in modern electronics covering broad applications ranging from transistors to logic circuits thanks to the output rectified signal in the…
Light-enhanced nonlinear Hall effect
Fang Qin, Rui Chen, Ching Hua Lee
It is well known that a nontrivial Chern number results in quantized Hall conductance. What is less known is that, generically, the Hall response can be dramatically different from…
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…
Field-Effect Josephson Diode via Asymmetric Spin-Momentum-Locking States
Pei-Hao Fu, Yong Xu, Shengyuan A. Yang +3
Recent breakthroughs in Josephson diodes dangle the possibility of extending conventional non-reciprocal electronics into the realm of superconductivity. While a strong magnetic fi…
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…
Observation of hybrid higher-order skin-topological effect in non-Hermitian topolectrical circuits
Deyuan Zou, Tian Chen, Wenjing He +4
Robust boundary states epitomize how deep physics can give rise to concrete experimental signatures with technological promise. Of late, much attention has focused on two distinct…
Universal model for electron thermal-field emission from two-dimensional semimetals
L. K. Ang, Yee Sin Ang, Ching Hua Lee
We present the theory of out-of-plane (or vertical) electron thermal-field emission from 2D semimetals. We show that the current-voltage-temperature characteristic is well-captured…
