Few-Mode and Anisotropic Quantum Transport in InSb Nanoribbons Using an All-van der Waals Material-Based Gate
Colin J. Riggert, Pim Lueb, Tyler Littmann +5
High-quality electrostatic gating is a fundamental ingredient for successful semiconducting device physics, and a key element of realizing clean quantum transport. Inspired by the…
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…
Evidence for -shifted Cooper quartets and few-mode transport in PbTe nanowire three-terminal Josephson junctions
Mohit Gupta, Vipin Khade, Colin Riggert +7
Josephson junctions are typically characterized by a single phase difference across two superconductors. This conventional two-terminal Josephson junction can be generalized to a m…
"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…
Diffusive and Ballistic Transport in Ultra-thin InSb Nanowire Devices Using a Few-layer-Graphene-AlOx Gate
Lior Shani, Pim Lueb, Gavin Menning +11
Quantum devices based on InSb nanowires (NWs) are a prime candidate system for realizing and exploring topologically-protected quantum states and for electrically-controlled spin-b…
Zero-bias conductance peaks at zero applied magnetic field due to stray fields from integrated micromagnets in hybrid nanowire quantum dots
Y. Jiang, M. Gupta, C. Riggert +7
Many recipes for realizing topological superconductivity rely on broken time-reversal symmetry, which is often attained by applying a substantial external magnetic field. Alternati…
Automatic Learning of Topological Phase Boundaries
Alexander Kerr, Geo Jose, Colin Riggert +1
Topological phase transitions, which do not adhere to Landau's phenomenological model (i.e. a spontaneous symmetry breaking process and vanishing local order parameters) have been…
Topological Effects in Tunneling-Coupled Systems of One-Dimensional Quantum Rings
Colin Riggert, Kieran Mullen
Using a model of idealized, crossed one-dimensional quantum wires we construct a novel model for a single electron on tunneling-coupled systems of one-dimensional quantum rings. We…
