Topological Magnons and Edge States in Antiferromagnetic Skyrmion Crystals
Sebastian A. Diaz, Jelena Klinovaja, Daniel Loss
Antiferromagnetic skyrmion crystals are magnetic phases predicted to exist in antiferromagnets with Dzyaloshinskii-Moriya interactions. Their spatially periodic noncollinear magnet…
Second Order Topological Superconductivity in -Junction Rashba Layers
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We consider a Josephson junction bilayer consisting of two tunnel-coupled two-dimensional electron gas layers with Rashba spin-orbit interaction, proximitized by a top and bottom $…
Chiral 1D Floquet topological insulators beyond rotating wave approximation
Dante M. Kennes, Niclas Müller, Mikhail Pletyukhov +6
We study one-dimensional (1D) Floquet topological insulators with chiral symmetry going beyond the standard rotating wave approximation. The occurrence of many anticrossings betwee…
Zero-energy Andreev bound states from quantum dots in proximitized Rashba nanowires
Christopher Reeg, Olesia Dmytruk, Denis Chevallier +2
We study an analytical model of a Rashba nanowire that is partially covered by and coupled to a thin superconducting layer, where the uncovered region of the nanowire forms a quant…
From fractional boundary charges to quantized Hall conductance
Manisha Thakurathi, Jelena Klinovaja, Daniel Loss
We study the fractional boundary charges (FBCs) occurring in nanowires in the presence of periodically modulated chemical potentials and connect them to the FBCs occurring in a two…
Lifetime of Majorana qubits in Rashba nanowires with non-uniform chemical potential
Pavel P. Aseev, Jelena Klinovaja, Daniel Loss
We study the lifetime of topological qubits based on Majorana bound states hosted in a one-dimensional Rashba nanowire (NW) with proximity-induced superconductivity and non-uniform…

Olesia Dmytruk, Denis Chevallier, Daniel Loss +1
We study analytically and numerically the renormalization of the -factor in semiconducting Rashba nanowires (NWs), consisting of a normal and superconducting section. If the pot…
Majorana Kramers pairs in higher-order topological insulators
Chen-Hsuan Hsu, Peter Stano, Jelena Klinovaja +1
We propose a tune-free scheme to realize Kramers pairs of Majorana bound states in recently discovered higher-order topological insulators (HOTIs). We show that, by bringing two hi…
Proximity effect in a two-dimensional electron gas coupled to a thin superconducting layer
Christopher Reeg, Daniel Loss, Jelena Klinovaja
There have recently been several experiments studying induced superconductivity in semiconducting two-dimensional electron gases that are strongly coupled to thin superconducting l…
Conductance of fractional Luttinger liquids at finite temperatures
Pavel P. Aseev, Daniel Loss, Jelena Klinovaja
We study the electrical conductance in single-mode quantum wires with Rashba spin-orbit interaction subjected to externally applied magnetic fields in the regime in which the ratio…
Rashba Sandwiches with Topological Superconducting Phases
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We introduce a versatile heterostructure harboring various topological superconducting phases characterized by the presence of helical, chiral, or unidirectional edge states. Chang…
Boundary spin polarization as robust signature of topological phase transition in Majorana nanowires
Marcel Serina, Daniel Loss, Jelena Klinovaja
We show that the boundary charge and spin can be used as alternative signatures of the topological phase transition in topological models such as semiconducting nanowires with stro…
Metallization of Rashba wire by superconducting layer in the strong-proximity regime
Christopher Reeg, Daniel Loss, Jelena Klinovaja
Semiconducting quantum wires defined within two-dimensional electron gases and strongly coupled to thin superconducting layers have been extensively explored in recent experiments…
