Comparison of Origins of Re-Entrant Supercurrents at High In-Plane Magnetic Fields in Planar InAs-Al Josephson Junctions
S. R. Mudi, S. Anupam, V. Mourik +1
Hybrid superconductor-semiconductor systems with large spin-orbit coupling are important platforms for realizing topological or triplet superconductivity. Planar Josephson junction…
Predicted third-order sweet spots for phi-junction Josephson parametric amplifiers
Tasnum Reza, Sergey M. Frolov
Hybrid superconductor-semiconductor nanowire Josephson junctions exhibit skewed and phi-shifted current phase relations when an in-plane magnetic field is applied along the weak li…
Matters Arising from S. Vaitiekenas et al., "Zero-bias peaks at zero magnetic field in ferromagnetic hybrid nanowires" Nature Physics 2021
C. Riggert, M. Gupta, Y. Jiang +3
In 2021 Nature Physics published a paper by Vaitiekenas, Liu, Krogstrup and Marcus titled "Zero-bias peaks at zero magnetic field in ferromagnetic hybrid nanowires". The paper repo…
Comment on "Ballistic Majorana Nanowire Devices" by Gul et al. Nature Nanotechnology 2018
S. M. Frolov, V. Mourik
This work re-analyzes Gul et al. Nature Nanotechnology 2018 "Ballistic Majorana nanowire devices" using fuller data from the original experiments released in 2023 on Zenodo. The au…
"Smoking gun" signatures of topological milestones in trivial materials by measurement fine-tuning and data postselection
S. M. Frolov, P. Zhang, B. Zhang +9
Exploring the topology of electronic bands is a way to realize new states of matter with possible implications for information technology. Because bands cannot always be observed d…
Evidence of 0-Josephson junction from skewed diffraction patterns in Sn-InSb nanowires
B. Zhang, Z. Li, V. Aguilar +10
We study Josephson junctions based on InSb nanowires with Sn shells. We observe skewed critical current diffraction patterns: the maxima in forward and reverse current bias are at…
Missing odd-order Shapiro steps do not uniquely indicate fractional Josephson effect
P. Zhang, S. Mudi, M. Pendharkar +10
Topological superconductivity is expected to spur Majorana zero modes -- exotic states that are also considered a quantum technology asset. Fractional Josephson effect is their man…
Large Second-Order Josephson Effect in Planar Superconductor-Semiconductor Junctions
P. Zhang, A. Zarassi, L. Jarjat +12
We investigate the current-phase relations of Al/InAs-quantum well planar Josephson junctions fabricated using nanowire shadowing technique. Based on several experiments, we conclu…
Model for missing Shapiro steps due to bias-dependent resistance
S. R. Mudi, S. M. Frolov
Majorana zero modes are predicted in several solid state systems such as hybrid superconductor-semiconductor structures and topological insulators coupled to superconductors. One o…
