InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Shadow-wall lithography of ballistic superconductor-semiconductor quantum devices
Sebastian Heedt, Marina Quintero-Pérez, Francesco Borsoi +14
The realization of a topological qubit calls for advanced techniques to readily and reproducibly engineer induced superconductivity in semiconductor nanowires. Here, we introduce a…
Interaction Driven Floquet Engineering of Topological Superconductivity in Rashba Nanowires
Manisha Thakurathi, Pavel P. Aseev, Daniel Loss +1
We analyze, analytically and numerically, a periodically driven Rashba nanowire proximity coupled to an -wave superconductor using bosonization and renormalization group analysi…
Quantum Brownian Motion of a Magnetic Skyrmion
Christina Psaroudaki, Pavel Aseev, Daniel Loss
Within a microscopic theory, we study the quantum Brownian motion of a skyrmion in a magnetic insulator coupled to a bath of magnon-like quantum excitations. The intrinsic skyrmion…
Degeneracy lifting of Majorana bound states due to electron-phonon interactions
Pavel P. Aseev, Pasquale Marra, Peter Stano +2
We study theoretically how electron-phonon interaction affects the energies and level broadening (inverse lifetime) of Majorana bound states (MBSs) in a clean topological nanowire…
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…
