One-dimensional topological superconductivity based entirely on phase control
Omri Lesser, Yuval Oreg, Ady Stern
Topological superconductivity in one dimension requires time-reversal symmetry breaking, but at the same time it is hindered by external magnetic fields. We offer a general prescri…
Local and Nonlocal Transport Spectroscopy in Planar Josephson Junctions
A. Banerjee, O. Lesser, M. A. Rahman +7
We report simultaneously acquired local and nonlocal transport spectroscopy in a phase-biased planar Josephson junction based on an epitaxial InAs/Al hybrid two-dimensional heteros…
Proximity-Induced Superconductivity in Epitaxial Topological Insulator/Graphene/Gallium Heterostructures
Cequn Li, Yi-Fan Zhao, Alexander Vera +16
The introduction of superconductivity to the Dirac surface states of a topological insulator leads to a topological superconductor, which may support topological quantum computing…
Renormalization-group-inspired neural networks for computing topological invariants
Gilad Margalit, Omri Lesser, T. Pereg-Barnea +1
We show that artificial neural networks (ANNs) can, to high accuracy, determine the topological invariant of a disordered system given its two-dimensional real-space Hamiltonian. F…
Signatures of a topological phase transition in a planar Josephson junction
A. Banerjee, O. Lesser, M. A. Rahman +12
A growing body of work suggests that planar Josephson junctions fabricated using superconducting hybrid materials provide a highly controllable route toward one-dimensional topolog…
