Spectral response of Josephson junctions with low-energy quasiparticles
Anna Keselman, Chaitanya Murthy, Bernard van Heck +1
We study nanowire-based Josephson junctions shunted by a capacitor and take into account the presence of low-energy quasiparticle excitations. These are treated by extending conven…
Evidence of topological superconductivity in planar Josephson junctions
Antonio Fornieri, Alexander M. Whiticar, F. Setiawan +13
Majorana zero modes are quasiparticle states localized at the boundaries of topological superconductors that are expected to be ideal building blocks for fault-tolerant quantum com…
From one-dimensional charge conserving superconductors to the gapless Haldane phase
Anna Keselman, Erez Berg, Patrick Azaria
We develop a framework to analyze one-dimensional topological superconductors with charge conservation. In particular, we consider models with flavors of fermions and $(\mathbb…
Topological Superconductivity in a Planar Josephson Junction
Falko Pientka, Anna Keselman, Erez Berg +3
We consider a two-dimensional electron gas with strong spin-orbit coupling contacted by two superconducting leads, forming a Josephson junction. We show that in the presence of an…
A Gapless Symmetry-Protected Topological Phase of Fermions in One Dimension
Anna Keselman, Erez Berg
We consider a one-dimensional, time-reversal-invariant system with attractive interactions and spin-orbit coupling. Such a system is gapless due to the strong quantum fluctuations…
Time-Reversal Invariant Topological Superconductivity Induced by Repulsive Interactions in Quantum Wires
Arbel Haim, Anna Keselman, Erez Berg +1
We consider a model for a one-dimensional quantum wire with Rashba spin-orbit coupling and repulsive interactions, proximity coupled to a conventional s-wave superconductor. Using…
