Intrinsic and Tunable Superconducting Diode Effect in Quantum Spin Hall Systems
Samuele Fracassi, Simone Traverso, Stefan Heun +3
Nonreciprocal dissipationless transport has long been sought for applications in superconducting technologies. Recently, it has been implemented by the so called superconducting di…
Supercurrent modulation in InSb nanoflag-based Josephson junctions by scanning gate microscopy
Antonio Lombardi, Gaurav Shukla, Giada Bucci +10
InSb nanoflags represent an interesting platform for quantum transport and have recently been exploited in the study of hybrid planar Josephson junctions. Due to the uncovered semi…
Superconducting Quantum Interference Devices based on InSb nanoflag Josephson junctions
Andrea Chieppa, Gaurav Shukla, Simone Traverso +10
Planar Josephson junctions (JJs) based on InSb nanoflags have recently emerged as an intriguing platform in superconducting electronics. This letter presents the fabrication and in…
Confinement-induced Majorana modes in a nodal topological superconductor
Simone Traverso, Niccolò Traverso Ziani, Maura Sassetti +1
We investigate the topological phase diagram of {an extension of the Haldane model with equal spin pairing superconductivity}. In two dimensions, we find a topological nodal superc…
Anomalous supercurrent and diode effect in locally perturbed topological Josephson junctions
Samuele Fracassi, Simone Traverso, Niccolò Traverso Ziani +3
The simultaneous breaking of time-reversal and inversion symmetry can lead to peculiar effects in Josephson junctions, such as the anomalous Josephson effect or supercurrent rectif…
Emerging topological bound states in Haldane model zigzag nanoribbons
Simone Traverso, Maura Sassetti, Niccolò Traverso Ziani
Zigzag nanoribbons hosting the Haldane Chern insulator model are considered. In this context, a reentrant topological phase, characterized by the emergence of quasi zero dimensiona…
An exact local mapping from clock-spins to fermions
Simone Traverso, Christoph Fleckenstein, Maura Sassetti +1
Clock-spin models are attracting great interest, due to both their rich phase diagram and their connection to parafermions. In this context, we derive an exact local mapping from c…
Effects of the Vertices on the Topological Bound States in a Quasicrystalline Topological Insulator
Simone Traverso, Niccolò Traverso Ziani, Maura Sassetti
The experimental realization of twisted bilayer graphene strongly pushed the inspection of bilayer systems. In this context, it was recently shown that a two layer Haldane model wi…
Role of the edges in a quasicrystalline Haldane model
Simone Traverso, Maura Sassetti, Niccolò Traverso Ziani
We study the role of the edges in determining the features of the topological phase in a quasicrystalline higher order topological insulator. We consider a specific model consistin…
