Tip-Tuned Renormalization-Group Spectroscopy Unmasks a False-positive Topological Superconducting Vortex
Zhenhua Zhu, Qun Zhu, Yong-Wei Wang +6
Clean, nonsplit vortex zero-bias peaks (ZBPs) can be misinterpreted as Majorana zero modes (MZMs), making static scanning tunneling microscopy intrinsically ambiguous. Here we use…
Coulomb blockade in open superconducting islands on InAs nanowires
Huading Song, Zhaoyu Wang, Dong Pan +8
Electrons in closed systems can exhibit Coulomb blockade (CB) oscillations due to charge quantization. Here, we report CB oscillations in aluminum superconducting islands on InAs n…
Quantized Andreev conductance in semiconductor nanowires
Yichun Gao, Wenyu Song, Yuhao Wang +20
Clean one-dimensional electron systems can exhibit quantized conductance. The plateau conductance doubles if the transport is dominated by Andreev reflection. Here, we report quant…
Gate-tunable subband degeneracy in semiconductor nanowires
Yuhao Wang, Wenyu Song, Zhan Cao +20
Degeneracy and symmetry have a profound relation in quantum systems. Here, we report gate-tunable subband degeneracy in PbTe nanowires with a nearly symmetric cross-sectional shape…
Anomalous Fraunhofer-like patterns in quantum anomalous Hall Josephson junction
Junjie Qi, Haiwen Liu, Jie Liu +5
The intriguing interplay between topology and superconductivity has attracted significant attention, given its potential for realizing topological superconductivity. In the quantum…
In situ tuning of dynamical Coulomb blockade on Andreev bound states in hybrid nanowire devices
Shan Zhang, Zhichuan Wang, Dong Pan +14
Electron interactions in quantum devices can exhibit intriguing phenomena. One example is assembling an electronic device in series with an on-chip resistor. The quantum laws of el…
Large Andreev bound state zero bias peaks in a weakly dissipative environment
Zhichuan Wang, Shan Zhang, Dong Pan +14
We study Andreev bound states in hybrid InAs-Al nanowire devices. The energy of these states can be tuned to zero by gate voltage or magnetic field, revealing large zero bias peaks…
Double Fu-teleportation and anomalous Coulomb blockade in a Majorana-hosted superconducting island
Yiru Hao, Gu Zhang, Donghao Liu +1
We study the temperature dependence of Coulomb Blockade peak conductance based on a Majorana-hosted superconducting island. In the low-temperature regime, we discover a coherent do…
Universal conductance scaling of Andreev reflections using a dissipative probe
Donghao Liu, Gu Zhang, Zhan Cao +2
The Majorana search is caught up in an extensive debate about the false-positive signals from non-topological Andreev bound states (ABSs). We introduce a remedy using the dissipati…
Suppressing Andreev bound state zero bias peaks using a strongly dissipative lead
Shan Zhang, Zhichuan Wang, Dong Pan +14
Hybrid semiconductor-superconductor nanowires are predicted to host Majorana zero modes, manifested as zero-bias peaks (ZBPs) in tunneling conductance. ZBPs alone, however, are not…
Large zero bias peaks and dips in a four-terminal thin InAs-Al nanowire device
Huading Song, Zitong Zhang, Dong Pan +11
We report electron transport studies of a thin InAs-Al hybrid semiconductor-superconductor nanowire device using a four-terminal design. Compared to previous works, thinner InAs na…
Topological Kondo Device for distinguishing Quasi-Majorana and Majorana signatures
Donghao Liu, Zhan Cao, Xin Liu +2
To confirm the Majorana signatures, significant effort has been devoted to distinguishing between Majorana zero modes (MZMs) and spatially separated quasi-Majorana modes (QMMs). Be…
